Abstract

A time-domain model of the leaky-wave radiation from a slot is assembled via an in-depth numerical investigation. The reported numerical experiments, all making use of a strictly causal excitation, provide a practical guideline for designing leaky-lens antennas (LLAs) and, above all, cogently elucidate the causal mechanism building up the propitious electromagnetic field distribution underpinning the LLA operation.
