Abstract
A microwave cavity device having close frequency resonant modes wherein the major portion of the electromagnetic field energy of each mode is localized in a different region of the cavity is presented. The device can comprise one or several inputs, one or several outputs and tuning elements. These, together with the localization of the modes make the device suitable for different applications such as filters, multiplexors, switches. A class of cavities presenting localized modes are disclosed. These cavities are used in embodiments which have the advantage of being relatively simple, compact, with low insertion loss, high quality factor and simple tuning. Such cavities can be coupled in larger structures.
