Paper Abstract

A novel periodic leaky-wave microstrip antenna is presented that is capable of dynamic beam scanning using optical control techniques. Optical control is achieved by illuminating silicon elements placed periodically along the length of the antenna with variable optical intensity. Incident photons absorbed into the surface of the silicon create an excess carrier concentration whose behavior within electromagnetic fields is characterized by a complex permittivity that is derived from first principles using Maxwell’s equations. Preliminary simulations validate the antenna concept.
