In this letter, we show that a cylindrical, single-layer impedance metasurface enclosing a radiating source is capable of reshaping the electromagnetic field pattern at a predetermined radius outside of the metasurface. We first present the design procedure of a cylindrical impedance metasurface and then proceed to an example demonstrating the achievable pattern accuracy. Simulation results validate...
In this paper, the design of a near-field shell is presented. A near-field shell is a single layer impedance sheet enclosing a radiating source that re-shapes the electromagnetic field pattern at a pre-determined image distance outside of the shell. The general design process for a cylindrical near-field shell, along with an example of a near-field shell using printed circuit board impedances to produce...
