Conformable and Controllable Radome in X Band using Electromagnetic Band Gap Material

We report the study of the design and the simulation of a conformable and switchable radome in X band (around 10 GHz) based on a controllable electromagnetic band gap material (CEBG) [1-4]. This material consists of parallel periodic metallic wires forming a grid. The introduction of active electronic elements such as PIN diodes or photoconductors, allows the commutation between the electric state of continuous wires and the state of discontinuous ones. We switch from the forbidden gap of an EBG material made of the continuous metallic wires lattice to the forbidden band of the periodic discontinuous wires one, according to the voltage or the light intensity. This structure must present a commutation around 10 GHz and finds various applications in the aeronautic field.
