Abstract

A transmitarray far-field beam scanning performance is illustrated based on the behavior of its focal region fields. It is shown that the oblique incidence of a plane wave on a transmitarray surface, forces the near-field focal point to shift mainly laterally with respect to the transmitarray surface. This behavior is shown useful in investigating a transmitarray far-field beam scanning. A beam scanning of 30 degrees is shown possible with no more than 1dBi gain loss.
