Abstract

A closed-form analytical solution is developed for predicting the early-time tran- sient electromagnetic fields which are generated by a perfectly conducting elliptical reflector antenna when it is illuminated by a transient step spherical wave due to an elemental Huygen’s source located at the focus near the surface. Furthermore we discussed a transient analysis of a hyperbolic reflector antenna is performed based on a mathematic continuation of surface curva- tures of an ellipsoidal reflector antenna. This work makes the time-domain (TD) analysis useful for the design of reflector antennas since both ellipsoidal and hyperbolic reflectors are widely used as sub-reflectors for dual-reflector antenna system.
