Abstract
An active artificial magnetic conductor includes a ground plane and an array of unit cells coupled to the ground plane. Each unit cell includes a low impedance shunt coupled to the ground plane and an impedance element coupled to the low impedance shunt. A plurality of non Foster circuits are coupled in two different directions between impedance elements of adjacent neighboring unit cells in the array of unit cells.
