Extended Ray Analysis of Electromagnetic wave Scattering from 3-D Smooth Objects

Abstract

When a plane electromagnetic short pulse is incident on an arbitrarily shaped smooth object, we have observed scattered pulses whose waveforms depend on polarizations of the incident pulse and the shape and material of scatterer [1]. To investigate the relation between scattered pulses and the shape of scatterer, we have analyzed these waveforms using the extended ray theory (ERT) that is a ray theory in the complex coordinate space and found several new anomalous aspects among scattered pulses from 2-D objects [1].
