This book was released on 2018-06-28 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conformal antenna arrays offer many cost and weight advantages over conventional antenna systems. In the past, antenna designers have had to resort to expensive measurements in order to develop a conformal array design. This is due to the lack of rigorous mathematical models for conformal antenna arrays, and as a result the design of conformal arrays is primarily based on planar antenna design concepts. Recently, we have found the finite element-boundary integral method to be very successful in modeling large planar arrays of arbitrary composition in a metallic plane. Herewith we shall extend this formulation for conformal arrays on large metallic cylinders. In this we develop the mathematical formulation. In particular we discuss the finite element equations, the shape elements, and the boundary integral evaluation, and it is shown how this formulation can be applied with minimal computation and memory requirements. The implementation shall be discussed in a later report. Kempel, Leo C. and Volakis, John L. and Woo, Alex C. and Yu, C. Long Unspecified Center NCA2-543...

This book was released on 2018-06-28 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conformal antenna arrays offer many cost and weight advantages over conventional antenna systems. However, due to a lack of rigorous mathematical models for conformal antenna arrays, antenna designers resort to measurement and planar antenna concepts for designing non-planar conformal antennas. Recently, we have found the finite element-boundary integral method to be very successful in modeling large planar arrays of arbitrary composition in a metallic plane. We extend this formulation to conformal arrays on large metallic cylinders. In this report, we develop the mathematical formulation. In particular, we discuss the shape functions, the resulting finite elements and the boundary integral equations, and the solution of the conformal finite element-boundary integral system. Some validation results are presented and we further show how this formulation can be applied with minimal computational and memory resources. Kempel, Leo C. and Volakis, John L.

Book excerpt: Within the United States, interest in conformal and low profile antennas is in response to space and airborne requirements, and also to the volume constraints of shipborne radar. Elements and arrays on generalized surfaces have also been analyzed using the finite difference time domain (FDTD) and finite element (FEM) methods. Analytical results for antennas on electrically larger bodies have been obtained using a combination of the Method of Moments (MOM) plus quasi-optical techniques. Recent work extends the utility of the hybrid methods using new Green's functions developed from the Uniform Geometrical Theory of Diffraction (UTD) to elevate the mutual coupling between elements on a uniformly coated, perfectly conducting, but otherwise arbitrarily shaped convex surface. In addition to advances in analytical treatments, a number of small arrays have been built conformal to cylinders and other metallic structures. Fully electronically scanned arrays have been developed for airborne satcom at SHF and EHF frequencies. Arrays with dimensions large compared to the local radius of curvature will also be discussed, including an ultra wide band UHF radar array.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this two-volume book is the systematic and comprehensive description of the most competitive time-domain computational methods for the efficient modeling and accurate solution of modern real-world EMC problems. Intended to be self-contained, it performs a detailed presentation of all well-known algorithms, elucidating on their merits or weaknesses, and accompanies the theoretical content with a variety of applications. Outlining the present volume, numerical investigations delve into printed circuit boards, monolithic microwave integrated circuits, radio frequency microelectromechanical systems as well as to the critical issues of electromagnetic interference, immunity, shielding, and signal integrity. Biomedical problems and EMC test facility characterizations are also thoroughly covered by means of diverse time-domain models and accurate implementations. Furthermore, the analysis covers the case of large-scale applications and electrostatic discharge problems, while special attention is drawn to the impact of contemporary materials in the EMC world, such as double negative metamaterials, bi-isotropic media, and several others.
