Observation of Brewster's Effect for Transverse-Electric Electromagnetic Waves in Metamaterials

by Y. Tamayama Physical Review B, 17 May 2006 We have experimentally realized Brewster's effect for transverse-electric waves with metamaterials. In dielectric media, Brewster's no-reflection effect arises only for transverse-magnetic waves. However, it has been theoretically predicted that Brewster's effect arises for TE waves under the condition that the relative permeability µr is not equal to unity. We have designed an array of split-ring resonators as a metamaterial with µr ≠ 1 using a finite-difference time-domain method. The reflection measurements were carried out in a 3-GHz region and the disappearance of reflected waves at a particular incident angle was confirmed. Read more
