Abstract
An active artificial magnetic conductor comprising an array of unit cells, each unit cell comprising an electrically conductive patch that is connected with an electrically conductive patch of neighboring unit cell in a column of unit cells using a non-Foster negative inductor and having RF isolating plates or walls between rows of unit cells. These isolating plates or walls eliminate undesirable cross coupling between the non-Foster negative inductors. The electrically conductive patches may be formed by metallic patches preferably arranged in the 2D array of such patches. Each patch preferably has a rectilinear shape.
