Abstract :
The radiation characteristics of a two-dimensional (2-D) periodic leaky-wave antenna at microwave and optical frequencies is examined. The phenomenon of directive beaming at optical frequencies can be explained in terms of leaky plasmon waves. These plasmonic structures are thus similar to a periodic 2-D leaky-wave antenna, and the fundamental radiation characteristics of them can be explained using leaky-wave theory.
