分析了在共面波导径向菱形短截线谐振腔的强磁场处引入缺口以提高品质因数的新方法。为了进行比较,在詹姆斯·瓦特纳米制造中心的砷化镓(GaAs)半绝缘衬底上制造了带有和不带有缺口的径向和钻石形共面波谐振器,并在格拉斯哥大学的毫米实验室进行了测试。缺口增加了约28%的金刚石谐振器的加载Q因子和良好的协议之间获得的测量和模拟加载的Q为共面波导径向和金刚石谐振器。© 2015威利期刊公司.微波光学技术快报57:1323-1325,2015
A novel method of introducing a notch at a point of high magnetic field in a coplanar waveguide (cpw) radial and diamond stub resonator to increase the quality factor (Q) was analyzed. For comparison, both radial‐ and diamond‐shaped cpw resonators with and without notches were fabricated on gallium arsenide (GaAs) semi‐insulating substrate at the James Watt Nanofabrication Centre and tested in the milli‐metric laboratory at University of Glasgow. The notch increased the loaded Q factor of the diamond resonator by approximately 28% and good agreement was obtained between the measured and simulated loaded Q for both cpw radial and diamond resonators. © 2015 Wiley Periodicals, Inc.
