Compact Rectangular Cavity for Rubidium Vapor Cell Frequency Standards,
Abstract
A new 6.8 GHz microwave cavity design for use in rubidium vapor cell frequency standards is discussed. The design consists of a rectangular cavity operating in the TE101 mode, partially loaded with a low loss dielectric slab. This configuration combines the desirable H-field uniformity of conventional cylindrical TE011 cavities with the reduced size advantage of cylindrical TE111 cavities. Careful selection of dimensions and dielectric material actually result in a resonator substantially smaller than even the cylindrical TE111 cavity, yet without significant degradation of field uniformity. Test results for a cavity based on this design in an operational Rb frequency standard are presented. (Author)
