Several new styles of radial klystron oscillators are studied theoretically and numerically. these new members include : the radial klystron oscillator with foldaway - concentric cylindrical cavity, the radial reflex klystron oscillator with virtual cathode and radial reflex klystron with open foldaway - concentric cylindrical cavity
它們是折疊式諧振腔徑向速調管振蕩器,高功率虛陰極徑向反射速調管振蕩器,開放式同軸折疊式諧振腔徑向反射速調管振蕩器。It is demonstrated that the transmission becomes tunable, depending on the thickness and the refraction index of the slabs deeply : as the thickness of lhm slab in the structure becomes wider, the bragg gap shifts toward higher frequency, in sharp contrast to its shift toward lower frequency as a result of widening the thickness of positive - index - material slab
然後利用傳輸矩陣法理論分析了這種結構的傳輸特性,證實了新帶隙的存在,同時發現結構的傳輸特性與結構組成介質的厚度以及折射率密切相關,當正折射物質的厚度增加時,傳統bragg帶隙會沿頻率軸向低頻方向移動,若為左手物質則向高頻方向移動。Experiments have demonstrated that, under the condition of constant temperature ( 20 ), the frequency error of double - frequency laser interferometer with two longitudinal modes could be controlled within 10 " 9 even with conditions such as with cool or hot air blowing, it can still be kept within 10 " 7. self - organised fuzzy control methods can be realised in a single - chip processor which contains fuzzy optimisation and self - organisation functions. the above - mentioned system possesses the following advantages : simple
/ znl (式中c為光速, l為諧振腔長, n為空氣折射率,其值約790mhz ) ,原理上對目前可能要求的測量速度都能滿足;它發出的光為一對互相垂直的線偏振光,與塞曼型雙頻激光干涉儀相比,它不用外加軸向磁場及1 / 4波片,因此結構簡單,造價低廉。If a optical anisotropic medium wafer is put into the mid of a polarizer and a analyser, the spectral transmission of the optical system can calculated. the transmission is determine by the birefringence and the thickness of the medium
對各向異性介質處于透光軸相互正交的兩個偏振片之間構成的光路,其光譜透過率與介質的延遲量有關,即與介質的雙折射特性和厚度有關。分享友人
