Abstract : A novel optically excited, frequency invariant, coplanar stripline antenna that we developed is presented, A comprehensive full wave analysis of optically excited coplanar striplines developed by us is also briefly reviewed. The work confirms the earlier hypothesis regarding the existence of new mechanisms. The reported findings imply the existence of a deeper and more fundamental physics underlying the optical generation, sensing and control of electromagnetic radiation. An extensive bibliography is provided. As of August 1991 the following characteristics have been achieved: Center frequency - N/A* Bandwidth 1THz (3 dB received power); Beam quality 99% TEB(oo) Gaussian; SNR 10(5), Energy output 25 femtojoules per pulse; Energy efficiency 0.003% (optical to electromagnetic).
