Book Terahertz Technology

Download or read book Terahertz Technology written by T. Anukiruthika and published by CRC Press. This book was released on 2023-08-22 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Terahertz (THz) technology is an active area of research, but only in recent years has the application of THz waves (T waves) in food and agricultural industries been explored. Terahertz Technology: Principles and Applications in the Agri-Food Industry describes the operating principles of THz technology and discusses applications and advantages of the THz regime of the electromagnetic spectrum for use in the agri-food industry. The agri-food industry is focusing on the development of non-destructive quality evaluation techniques that can provide accurate analysis quickly and are environmentally friendly. Among such techniques is THz technology that provides a novel noninvasive approach to quality assessment and safety assurance of agri-food products. The low energy of T waves is best suited for the analysis of sensitive biomaterials and does not cause photoionization. Therefore, THz imaging is complementary to X-ray imaging. Although accessing the THz spectrum is tedious by conventional devices, the combination of optics and electronics principles has opened a dimension of research in this field. This book provides an overview of THz spectroscopy and imaging, system components, types of THz systems, and applications and advantages of THz for applications in the agri-food industry. It describes the basic working mechanism, operating principle, operation modes, and system components of THz spectroscopy and imaging. Various advancements in THz technology related to agricultural and food applications are discussed that could serve as a guidebook for all those working and interested in non-destructive food assessment techniques. Key Features: Explores broader applications of the THz regime in the agri-food sector Describes system components, different forms of THz systems, and the working principle of T waves for spectroscopic and imaging techniques Provides insights on future research needs for industrial implementation of THz technology Complements the knowledge of other existing non-destructive spectroscopy and imaging techniques for food analysis Although books on biomedical applications of THz have been published, no book is available that deals with applications in the agri-food industry. Hence, Terahertz Technology is beneficial for undergraduate and graduate students and those food industry professionals involved in research related to non-destructive quality assessment and imaging techniques.

Book excerpt: Every bit of information that circulates the internet across the globe is a pulse of light, that at some point will need to be converted to an electric signal in order to be processed by the electronic circuitry in our data centers, computers, and cell phones. Photodetectors (PD’s) perform this conversion with ultra high speed and efficiency, in addition to being ubiquitously present in many other devices ranging from the mundane TV remote controls, to ultra high resolution instrumentation used in Laser Interferometer Gravitational Wave Observatory (LIGO) that reach the edge of the universe and measure gravitational waves. The second edition of "Photodetectors" fully updates the popular first edition with updated information covering the state-of-the-art in modern photodetectors. The 2nd edition starts with basic metrology of photodetectors and common figures-of-merit to compare various devices. It follows with chapters that discuss single-photon detection with Avalanche Photodiodes; organic photodetectors that can be inkjet printed; and silicon-germanium PDs popular in burgeoning field of Silicon Photonics. Internationally recognized experts contribute chapters on one-dimensional, nanowire, PDs as well as high speed zero-dimensional, quantum dot, versions that increase the spectral span as well as speed and sensitivity of PDs and can be produced on various substrates. Solar-blind PDs that operate in harsh environments such as deep space, or rocket engines, are reviewed and new devices in GaN technology . Novel Plasmonic PDs, as well as devices which employ micro-plasma of confined charge in order to make devices that overcome speed limitation of transfer of electronic charge, are covered in other chapters.

Book Applications of Electromagnetic Waves

Download or read book Applications of Electromagnetic Waves written by Reza K. Amineh and published by MDPI. This book was released on 2021-01-20 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electromagnetic (EM) waves carry energy through propagation in space. This radiation associates with entangled electric and magnetic fields which must exist simultaneously. Although all EM waves travel at the speed of light in vacuum, they cover a wide range of frequencies called the EM spectrum. The various portions of the EM spectrum are referred to by various names based on their different attributes in the emission, transmission, and absorption of the corresponding waves and also based on their different practical applications. There are no certain boundaries separating these various portions, and the ranges tend to overlap. Overall, the EM spectrum, from the lowest to the highest frequency (longest to shortest wavelength) contains the following waves: radio frequency (RF), microwaves, millimeter waves, terahertz, infrared, visible light, ultraviolet, X-rays, and gamma rays. This Special Issue consists of sixteen papers covering a broad range of topics related to the applications of EM waves, from the design of filters and antennas for wireless communications to biomedical imaging and sensing and beyond.

Book Superconductor Insulator Superconductor Mixer Devices with Gold Energy Relaxation Layers

Download or read book Superconductor Insulator Superconductor Mixer Devices with Gold Energy Relaxation Layers written by Stefan Selig and published by Cuvillier Verlag. This book was released on 2017-01-17 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Superconductor insulator superconductor (SIS) mixers are used in heterodyne receivers for radio-astronomical observations. The high frequency resolution of the heterodyne technique combined with the high sensitivity of SIS mixers enables high resolution spectroscopy of the interstellar medium. This work focuses on the development of a novel superconductor insulator superconductor (SIS) mixer technology for 800 GHz that could in the future be used up to 1.1 THz. This is an important part of the THz spectrum that is still accessible for astronomy from ground based observatories. Compared to the existing mixers in this frequency regime the sensitivity shall be improved by the use of fully superconducting radio-frequency (RF) matching circuits. The main innovation in this work is the inclusion of an energy relaxation layer made of gold that enables the use of these fully superconducting RF circuits in combination with the mature niobium SIS junction technology. The energy relaxation layer prevents heating of the SIS junction due to Andreev reflection at the interface between the junction electrode and the matching circuit transmission line which was observed in earlier developments. This work includes the development of a fabrication process as well as extensive DC and RF measurements and their interpretation.
