A study on band structure of Chiral medium

Abstract

In this thesis we discuss the first and second band of chiral medium and derivate the interface conditions for obtaining electromagnetic plane wave solutions Owing to the complicated determinant of coefficient matrix we cannot obtain the explicit relation of frequency and wavenumber of chiral medium directly Thus we propose the numerical method to overcome this difficulty Furthermore we apply finite difference method to solve the eigenvalue problem and substitute the frequency into the determinant of coefficient matrix And we investigate the rate of convergences From the numerical results we obtain the second-order convergences of the first and second band Besides we discover forth-order convergences when wavenumber of z component is equal to zero
