Perfect Electromagnetic Conductor and Fractional Dual Interface Placed in a Chiral Nihility Medium

Abstract

The reflection of plane wave from a perfect electromagnetic conductor (PEMC) and fractional dual interface placed in a chiral nihility medium is determined. It is noted that for both the cases reflected field is a backward wave. Electric and magnetic fields associated with the reflected wave do not cancel the corresponding electric and magnetic fields associated with the incident wave. It is also noted that in each case time average of the total power yields zero result, that is, the time average of the power incident on the interface cancels the time average of the reflected power. Chiral nihility waveguides, in which power may be confined to certain regions of the waveguide, are proposed.
