  1. The most achievement is that we firstly obtain the analytic accurate solution of the modal fields of the waveguide structure and find some available character : ( 1 ) the different uniaxial crystal materials have the different propagation properties ; ( 2 ) when the optical axis of the crystal is on the plane that is made up of the normal direction of the waveguide plane and the propagation, there are te mode and tm mode in this special waveguide, but the principal mode is different of the character of the uniaxial crystal, the principal mode is the principal mode of te mode for the negative uniaxial crystal, but the one of tm mode for the positive uniaxial crystal ; ( 3 ) when the crystal optical - axis parallel to the waveguide plane, for the positive uniaxial crystal material, the principal mode of the waveguide is a te wave, which can be excited by the light at any frequency ; when the light frequency satisfies a single mode propagation condition, there will be only the principal mode propagating in the waveguide, otherwise some of the higher order modes can be excited, which are neither te modes, nor tm modes, but the hybrid guided modes

    文就是在此背景下,利用金屬波導和單體的些特性,結合麥克斯韋方程組和波導的邊界條件,從三種不同的情況研究了在對稱平面單體金屬波導(波導層是單體,兩個波導界面均為金屬)內的傳輸特性,其主要貢獻為,首解析地得到了這種波導結構下模式場的精確解,並發現了些有用的特性: ( 1 )模式場的性質因單體的性質不同而異; ( 2 )當單位於波導界面法方向與傳輸方向構成的平面內時,波導中傳輸te波和tm波,只不過其主模因單體的性質不同而異,當波導層介質為負單體時,波導主模是te波主模,而波導層介質為正單體時波導主模是tm波主模。 ( 3 )當單位於波導面內時,對于正單體,波導的主模是橫電波te _ 0模,任何頻率的波均可激勵該模式;當波波長滿足定條件時,波導內傳輸單模,否則,將激勵起高階模式,高階模即匪te波,也匪tm波,而是兩者耦合而成的混合模。
