Novel photonically controlled antenna for MMW communications

We describe a new optically-controlled, narrow beam antenna for point to point communications. A computer controlled light source photo-injects a spatially varying plasma into a photoconducting wafer for MMW beam control. Antennas based on this approach are inexpensive and offer many advantages.
