Emerging technology for transient and broad-band analysis and synthesis of antennas and scatterers
Abstract
The historical background of the study of transient and continuous wave electromagnetic phenomena is considered, the basic equations are presented, integral equations are examined, and approaches to the solution of the transient/broadband problem are explored. The numerical inverse Fourier transform of frequency-domain solutions is discussed and a description is presented of the analytic s plane approach, taking into account the low-frequency method, the singularity expansion method, and the high-frequency method. Attention is also given to the eigenmodes of frequency-domain integral equations, finite-difference time-domain solutions, time-domain integral equations, approximate transmission-line models of thin antennas and scatterers, and closed form transient solutions for special geometries.
