This book was released on 2018-07-03 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Application of Asymptotic Waveform Evaluation (AWE) is presented in conjunction with a hybrid Finite Element Method (FEM)/Method of Moments (MoM) technique to calculate the input characteristics of cavity-backed aperture antennas over a frequency range. The hybrid FEM/MoM technique is used to form an integro-partial-differential equation to compute the electric field distribution of the cavity-backed aperture antenna. The electric field, thus obtained, is expanded in a Taylor series around the frequency of interest. The coefficients of 'Taylor series (called 'moments') are obtained using the frequency derivatives of the integro-partial-differential Equation formed by the hybrid FEM/MoM technique. Using the moments, the electric field in the cavity is obtained over a frequency range. Using the electric field at different frequencies, the input characteristics of the antenna are obtained over a wide frequency band. Numerical results for an open coaxial line, probe fed cavity, and cavity-backed microstrip patch antennas are presented. Good agreement between AWE and the exact solution over the frequency range is observed. Reddy, C. J. and Deshpande, M. D. Langley Research Center NCC1-231; RTOP 522-33-11-02...

This book was released on 2012-12-06 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the first ICASE/LaRC Work shop on Computational Electromagnetics and Its Applications conducted by the Institute for Computer Applications in Science and Engineering and NASA Langley Research Center. We had several goals in mind when we decided, jointly with the Elec tromagnetics Research Branch, to organize this workshop on Computa tional Electromagnetics ( CEM). Among our goals were a desire to obtain an overview of the current state of CEM, covering both algorithms and ap plications and their effect on NASA's activities in this area. In addition, we wanted to provide an attractive setting for computational scientists with expertise in other fields, especially computational fluid dynamics (CFD), to observe the algorithms and tools of CEM at work. Our expectation was that scientists from both fields would discover mutually beneficial inter connections and relationships. Another goal was to learn of progress in solution algorithms for electromagnetic optimization and design problems; such problems make extensive use of field solvers and computational effi ciency is at a premium. To achieve these goals we assembled the renowned group of speakers from academia and industry whose talks are contained in this volume. The papers are printed in the same order in which the talks were pre sented at the meeting. The first paper is an overview of work currently being performed in the Electromagnetic Research Branch at the Langley Research Center.

This book was released on 2018-10-25 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: A combined finite element method (FEM) and method of moments (MoM) technique is presented to analyze the radiation characteristics of a cavity-fed aperture in three dimensions. Generalized feed modeling has been done using the modal expansion of fields in the feed structure. Numerical results for some feeding structures such as a rectangular waveguide, circular waveguide, and coaxial line are presented. The method also uses the geometrical theory of diffraction (GTD) to predict the effect of a finite ground plane on radiation characteristics. Input admittance calculations for open radiating structures such as a rectangular waveguide, a circular waveguide, and a coaxial line are shown. Numerical data for a coaxial-fed cavity with finite ground plane are verified with experimental data. Reddy, C. J. and Deshpande, M. D. and Cockrell, C. R. and Beck, F. B.

Book Synopsis Frequency and Transient Characteristics of MMIC Transmission Lines, Circuits and Antennas by :
Download or read book Frequency and Transient Characteristics of MMIC Transmission Lines, Circuits and Antennas written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The frequency characteristics of two dimensional planar MMIC transmission lines and circuits, three dimensional electronic packaging circuits, and cavity backed aperture and microstrip antennas loaded with dielectric and/or magnetized ferrite materials were analyzed using advanced full wave analytical and numerical techniques, such as the Finite Element Method (FEM) and Method of Moments / Spectral Domain Approach (MoM/SDA). For the two dimensional planar transmission lines the propagation characteristics examined included the effective dielectric constant, attenuation constant, and characteristic impedance. Anisotropic materials, such as sapphires, PTFE cloth, and ferrites were also modeled and analyzed. Substrate compensation was used in multilayer, multiconductor lines to minimize coupling and pulse distortion. A three dimensional vector finite element code was developed to simulate practical electronic packaging circuits, including microstrip / coplanar discontinuities, spiral inductors, filters, conducting vias, etc. A hybrid FEM/MoM approach was used in the analysis and design of cavity backed aperture and microstrip antennas loaded with dielectric and/or magnetized ferrite materials. The magnetization of the ferrite was used to tune the cavity over an extended bandwidth. In addition, analytical techniques were developed to evaluate efficiently and accurately the asymptotic matrix elements using the MoM/SDA. The computational efficiency was improved, in some cases, by a factor of 50 compared to conventional methods.
