本文就是在此背景下,利用金屬波導和單軸晶體的一些特性,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光在對稱平面單軸晶體金屬波導(波導層是單軸晶體,兩個波導界面均為金屬)內的傳輸特性,其主要貢獻為,首次解析地得到了這種波導結構下模式場的精確解,並發現了一些有用的特性: ( 1 )模式場的性質因單軸晶體的性質不同而異; ( 2 )當單軸晶體光軸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,只不過其主模因單軸晶體的性質不同而異,當波導層介質為負單軸晶體時,波導主模是te波主模,而波導層介質為正單軸晶體時波導主模是tm波主模。 ( 3 )當單軸晶體光軸位於波導面內時,對于正單軸晶體,波導的主模是橫電波te _ 0模,任何頻率的光波均可激勵該模式;當光波波長滿足一定條件時,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。In chapter four, using the quantum statistics method we study the cohesion of a metallic nanowire irradiated under electromagnetic wave based on the results in chapter three. we obtain that the cohesion force is effected notably only when the frequency of electromagnetic field is at the vicinity of the energy span of the lateral levels of the nanowire
第四章以第三章的工作為基礎,用量子統計的方法,分析了太赫茲電磁波部分輻照對金屬納米線內聚力的影響,得到了只有當外場頻率與橫向模式共振時內聚力才有顯著變化的結論。A new waveguide made of changing a wide wall of a rectangular waveguide to a uniform curved wall is called conformal waveguide. a kind of expression of approximate solution for domain mode of the new waveguide, including symmetric, unsymmetric arc, parabolic arch, hyperbolic arch, elliptic arch, etc., is constructed by using boundary condition of mental waveguide, variational method and boundary element method. by using the equivalence principle, an approximate calculating formula for equivalent resonant conductance of a narrow longitudinal halfwavelength slot cut in the curved wall of the unsymmetric arcrectangular waveguide is derived, and the result is shown. although this solution is approximate, it can solve the problem in designing the slotted antenna of such conformal waveguide
把矩形波導一個寬面外突成均勻曲面構成的新波導統稱為共形波導.利用金屬波導邊界條件、變分法、邊界元素法構造這種新波導中主模場的一種近似解表達式,包括曲面橫截線為對稱、非對稱圓弧,拋物線弧,雙曲線弧,橢圓弧等.然後根據等效原理,推導非對稱圓弧矩形波導曲面上窄的縱向半波長縫隙的等效諧振電導的近似計算公式,給出計算曲線.這種解雖然是近似的,但卻能解決這類共形波導縫隙天線的工程設計The possible factors including the deviation of temperature in length and breadth of rod, the changes of transfiguration resisting force under the changes of temperature, the adjustment of roll gap, the variation of rolling pressure, the changes of roller speed during dynamic adjusting press, the unmatched of seconds - flux under the dimension fluctuation of the coming sample and so on. the whole system was a closed loop which factors in it interacts each other
可能的影響因素有:沿軋件縱橫向溫度變化、由溫度引起的軋件變形抗力變化、軋機輥縫值變化、負載變化、電機調節系統由不穩定向穩定過渡過程中軋輥轉速的變化(如咬鋼過程中的動態速降后的回復階段) 、來料尺寸波動造成秒流量不匹配等,整個模擬系統是各個因素相互影響關聯的一個閉環系統。When the isotropic waveguide is under the isotropic disturbances, the coupling term due to polarization, which is presented in the coupled - mode theory of the wei - ping huang, is n ' t included in this rigorous vectorial coupled - mode theory, exactly, the rigorous vectorial cmt does n ' t contain the coupling term due to polarization which is include in the scalar coupled - mode theory because this term is counteracted with the other coupling term neglected under weakly guiding approximation. as for anisotropic disturbances, we get the coupled - mode equations with arbitrary dielectric tensors. from them, we obtain the coupled - mode equations of the slowly varying term c ( z ) which is more simplicity
當受到各向同性微擾時,我們發現嚴格的矢量理論所得到的耦合系數表達式中並不包括wei - pinghuang的理論中的偏振耦合項,更確切的說,偏振耦合項正好與因弱導近似而忽略的項相抵消,這就是標量理論所得到結果(有偏振耦合項)與矢量理論在標量近似下的結果(不含偏振耦合項)不一致的原因所在;當各向異性微擾時,我們得到了包含微擾介電張量各個分量的橫電磁場耦合波方程,討論了微擾介電張量各個分量對耦合的影響,而且從橫電磁場耦合波方程出發得到了形式更加簡單的只含有橫電場系數的緩變分量c _ ( z )的耦合波方程和耦合系數表達式,並以弱導近似下的單模光纖兩正交偏振模耦合為例對耦合系數在不同條件下的取捨做了定性的分析。Transverse electromagnetic cell

本論文研究了一種質子交換linbo3溝道波導共線式聲光偏轉器,其特點是利用了溝道波導的橫向約束,限制了聲波的發散和衍射效應,使得窄孔徑電極結構得以實現,從而增加了功率密度,使總的聲場驅動功率降低。Although light waves in the regime of classical optics can have electric fields as strong as those near bolts of lightning, these fields are not effective for accelerating particles on their own, because they oscillate transversely
在古典光學中,雖然光波的電場有可能大到如閃電雷擊的程度,但因為電場是以橫向振蕩的,所以無法有效用來加速粒子。Transverse electromagnetic mode
