A Parametric Study of Microwave Reflection Characteristics of a Planar Achiral-Chiral Interface

The microwave reflection characteristics of a planar achiral-chiral interface have been examined by setting the transmitted EM field in the chiral half-space in terms of left and right circularly polarized waves. The reflected field in the achiral half-space is seen to be circularly polarized. From the numerical data presented it is concluded that by utilizing refracting media with chiral microgeometries an increase or a decrease in the reflected power can be effected. Conceivably, therefore, such materials can be tailor-made to suit specific requirements, such as in the design of anechoic chambers.
