Prof. Felipe Cátedra, CEO of newFASANT and Professor at University of Alcalá, Madrid, Spain, will be at “Microwave Theory & Techniques” and “Antennas & Propagation” Societies Meeting, doing an overview of different numerical solvers for electromagnetic applications. The meeting will take place at Arizona State University, Goldwater Center, GWC487 650 E. Tyler Mall, Tempe, AZ, from 5PM to 7:30PM, Friday, May 22, 2015.
An overview shall be provided for numerical solvers used for the analysis of arbitrary electromagnetic problems, including GO (Geometric Optics), PO (Physical Optics), GTD (Geometrical Theory of Diffraction), UTD (Uniform Theory of Diffraction), Stationary Phase Method (SPM), MoM (Method of Moments), MLFMM (Multilevel Fast Multipole Method), CBFM (Characteristic Basis Functions Method), etc. The applications for these numerical solvers to various analysis and design problem geometries shall be discussed, specific solvers to be used for problem categories shall be identified, the limitations of each solver shall be identified, the computer resources required for each solver shall be defined, the accuracy achievable for each solver shall be defined, etc.
A discussion of the different errors that can be encountered with these solvers including the meshing steps and methods to use to avoid these errors will be discussed. Several applications for the solvers will be addressed: RCS (Radar Cross Sections) of any target alone, above sea/land, and with/without RAM (Radar Absorbing Material) coatings; large antennas like reflectors (cassegrain, inverse cassegrain, conformal surfaces, and relfectarrays/transmitarrays) and phased arrays; antenna placement on large platforms; patch antennas and surface conformed antennas; MIMO (Multiple Input Multiple Output) systems; automobile antennas; radiowave propagation indoor, urban (outdoor), and rural scenarios, etc.
