Abstract
A dynamic aperture is disclosed. A dynamic aperture includes a base layer, a conductive structure disposed on the base layer, and a layer of a material having a dynamically controllable electrical conductivity that is disposed over the base layer and the conductive structure. A transmission profile of the dynamic aperture is determined by a combination of the conductive structure and the layer of the material. The transmission profile is dynamically alterable by controlling the electrical conductivity of the layer of the material.
