Abstract

We theoretically study the resonant properties of an aggregate of coupled cylinders filled with negative permittivity plasma. Such a problem has applications in optical and plasma antennas, intelligent antenna systems, and pulse-driven antenna arrays. Chain of columns of plasma can be used in the design of both transmitting and receiving antennas with a very broad frequency range and tunability that allows switching it on and off very fast. The Mie series expansion is used to derive the solution. Electromagnetic analysis of the spectrum of different plasmon resonances is presented.
