Electromagnetic Beam Propagation Through Dispersive Material

Abstract

The objective of AFOSR grant 'Electromagnetic Beam Propagation Through Dispersive Material'' (FA9550-16-1-0241) was to analyze the propagation of both pulsed waves and pulsed beam fields through dispersive material using asymptotic techniques. Asymptotic methods provide valuable approximations based upon the full, causal electromagnetic response of the dispersive material over all frequencies. In this reporting period, we have continued to analyze waveforms for synthetic aperture radar through dispersive material and have continued to investigate asymptotic methods for multiple integrals with complex phase.
