Theoretical study of Electromagnetic Waves in Chiral media: about Nonlinearity & Multilayers

Chiral 매질에서, 전자기파의 비선형성과 여러겹 구조에서의 Coupled-mode theory에 관한 연구

We analyze the nonlinearity of chiral media and coupled-mode theory of chiral multilayers. In first topic, second order nonlinear coupled equations are constructed and a phase matchine method is suggested. This approach can be developed to higher order nonlinearity and electric-field-induced second harmonic generation. In second topic, coupled mode equation in chiral multilayers is constructed, and solved for both codirectional coupling and contradirectional coupling. There is a previous formulation about chiral mutilayers[1] with 4$\times$4 matrix but it did not give detail results, so this approach will be compared with that.
