Parametric Experimental Study of Microwave Absorption in Chiral Composites
Abstract
Theoretical and experimental studies have shown that chiral composites constructed by embedding chiral inclusions in an otherwise achiral lossy medium enhance power absorption in the microwave frequency range. Chiral composites can hence be used as microwave absorbers to achieve rapid heating during microwave processing of ceramics, glass, and composites. Power absorption bands of chiral composites are discussed and the corresponding ratio of the one turn length of the chiral inclusion to the wavelength in the medium L/Lambda c are reported. This ratio can be used to optimize absorption at different operating frequencies. Experimental studies on chiral composites having different sizes of chiral inclusions are also included.
