Coordinate transformation applied to change physical appearance of radiating sources

Abstract : The use of transformation optics concept to change the physical size of radiating sources is investigated. By choosing transformations that compress space, and then match it to the surrounding radiation environment, we are able to miniaturize the physical size of the embedded source. We show that a small aperture antenna can then behave as one with a large aperture. A study of the transformation of the space metric and the material parameter calculation is presented. Simulations are performed to validate the proposed approach at microwave frequencies. This study paves the way to interesting applications in telecommunications and aeronautical domain.
