Abstract :
An extremely small and inexpensively manufactured physics package for an atomic frequency standard can be provided with a microwave cavity having non-critical dimensions that is driven in a substantially TEM mode by a lumped LC structure inside a hollow, substantially closed, conducting enclosure. The enclosure can be a cylinder with rectangular or circular cross section. If this cavity is formed by modifying a coaxial cavity, the outer conductor will be the enclosure, and the inner conductor, shorted to at least one of the walls, with a gap at the other end, will be the lumped LC. The resonant frequency of the cavity is primarily determined by the capacitance of the lumped C and the inductance of the inner conductor
