Excitation of whispering gallery modes in shielded dielectric resonators by #x201C;slot-line#x201D;

摘要

Open dielectric resonators (DRs) as disk and ball with whispering gallery modes (WGMs) have well known advantages such as a high value of Q-factor in millimeter band of wavelength [1]. However they have disadvantages when used in specific devices and appliances (below).
