Abstract
Official abstract text for this publication.
A tunable impedance surface, the tunable surface including a plurality of elements disposed in a two dimensional array; and an arrangement of variable negative reactance circuits for controllably varying negative reactance between at least selected ones of adjacent elements in the aforementioned two dimensional array.
First claim
Opening claim text (preview).
What is claimed is: 1. A tunable impedance surface, the tunable impedance surface comprising: (a) a plurality of elements disposed in a two dimensional array; and (b) a plurality of non-Foster circuits for controllably varying a negative inductance or capacitance between at least selected ones of adjacent elements in said two dimensional array. 2. The tunable impedance surface of claim 1 further including a substrate having first and second major surfaces, sai…
