Paper Abstract

Versatile control of the microwave signature of a complex object under the command of a central/local processor(s) requires a bias/communications network to be embedded in a smart surface treatment and distributed over distances small compared to the shortest wavelength of interest. One requirement of the system is that the bias and microwave signal paths be isolated for all configurations of the smart surface. It is also required that the surface impedance of the treatment satisfy an impedance boundary condition to allow the processor to use an efficient electromagnetic computational code. A design approach that accommodates these requirements incorporates the bias conductors as an integral constituent of a new smart microwave material called an `effective surface;' the two dimensional equivalent of an effective media.
