Experimental demonstration of reflection minimization at two-dimensional photonic crystal interfaces via antireflection structures

Teun-Teun Kim, Sun-Goo Lee, Myeong-Woo Kim, Hae Yong Park, and Jae-Eun Kim
We experimentally confirm that the antireflection structures effectively minimize unnecessary reflections of self-collimated microwave beams at the interfaces of a two-dimensional photonic crystal, which is composed of cylindrical alumina rods. Optimized design parameters for the antireflection stru ... [Appl. Phys. Lett. 95, 011119 (2009)] published Fri Jul 10, 2009.
