  2. Abstract : in the field of optical wireless links, concentrators that are designed by the tools of nonimaging optics can be used to collect the light radiation and are more compact and have higher collection efficiencies than imaging concentrators. hemispherical concentrators are studied by ray tracing, then for several normal nonimaging concentrators : hemispherical concentrators, compound parabolic concentrators ( cpc ), dielectric totally internally reflecting concentrators ( dtirc ), simultaneous multiple surfaces concentrators ( sms ) and inhomogeneous media concentrators ( poisson bracket ), the design methods and the performances e. g. the gain and the field of view ( fov ) are compared as well as the application suggestion

    文摘:在無線光通信領域，利用非成像光學設計的集中器能夠聚集光輻射能量，而且相對于成像性集中器具有更緊湊的結構和更高的增益.利用光線追跡法對半球形集中器的性質進行了分析與研究.對好幾種非成像集中器:半球形集中器，復合拋物線形集中器，介質內部全反射集中器，多表面集中器，多相介質集中器，從設計原理、增益和視場進行比較，並分析其應用場合
  3. The design of amorphous photonic material and photonic crystal devicements we design to make a reflecting mirror of cylinder paraboloid of an antenna by using amorphous photonic materials. we calculated the transmission of the mirror and the distribution of electric field by using multiple scattering method. the result shows that it can be used as a reflecting mirror of an antenna

    非晶光子材料和光子晶體器件的設計提出了用介質圓柱光子晶體作微波天線的柱拋物面反射鏡，用多重散射方法計算了反射鏡的透過譜，並模擬計算了天線的電場分佈，初步認為可以用非晶光子材料作微波天線的反射鏡。
  4. After the comparing the simulation results with the theoretic results under the three followed condition : a point light source on the parabola reflector focus, a point light on the ellipsoid reflector focus and a point light source before the parabola reflector focus, a conclusion is gotten that the two results are generally accordant, the accuracy of the simulation software reach the engineering requirements and the computational simulation software of photometric characteristics of headlamp of motor vehicles can guide the design of the headlamp reflectors

    比較了點光源位於拋物面反射器和橢球面反射器焦點的情況和點光源偏離拋物面焦點的情況下照度的理論計算結果和採用本文的照度模擬計算結果，其模擬計算結果和理論計算結果基本相符，能滿足工程上的要求，說明模擬計算軟體對前照燈的反射鏡的設計具有很好的指導意義。
