Abstract
Here we report a prism made of stacked quasi-self- complementary extraordinary transmission surfaces which allows simultaneously left- and right-handed propagation within the V-band for vertical and horizontal polarizations, respectively and right-handed propagation within the W-band for both polarizations. The numerical dispersion diagram of the inflnite structure and efiective indexes of refraction retrieved from S-parameters under normal incidence together with the flnite integration time domain simulations predict single negative and double positive birefringence. The unusual type of birefringence single negative and regular double positive birefringence are afterwards demonstrated experimentally at the millimeter-waves (V- and W-bands) by the wedge experiment which lets us check, using a straightforward geometrical method, the refraction of each component. The efiective index of refraction is retrieved via the Snell's law and compared to those obtained through the dispersion diagram and the retrieval method from S-parameters computed with the commercial software CST Microwave Studio TM .
