Speaker: Dr. C.J. Reddy
Speakers' Title: Vice President, Business Development - Electromagnetics, Americas at Altair Engineering, Inc.
Seminar Title: Antenna Modeling and Simulation Techniques
Abstract:
Now-a-days antennas have become an integral and important part of almost any wireless communication system. In the field of antenna engineering, theoretical analysis is of paramount importance in understanding the basics of the antenna radiation characteristics. While the basic concept of antennas is well known, closed form, exact analytical solutions to many antenna problems are not practical and impossible in many cases. Advances in electromagnetic (EM) simulations have significantly impacted the antenna design process by providing exact solutions by solving Maxwell’s equations using numerical methods. It is a common practice now in academia and industry to use various commercially available EM simulation tools for antenna design process. In this talk, we will introduce basics of antenna modeling and simulation process with pros and cons of various numerical methods, such as Method of Moments (MoM), Multilevel Fast Multipole Method (MLFMM), Finite Element Method (FEM), Finite Difference Time Domain (FDTD), Physical Optics (PO), Ray Lunching Geometrical Optics (RL-GO) (also known as Shooting and Bouncing Ray – SBR method), and Uniform Theory of Diffraction (UTD) that are available in Altair Feko.
