The study consists of an examination of a unique technique for measuring the modes within a waveguide. The technique provides for electric field intensity measurements in a waveguide by using a pool of mercury as one side of a waveguide section. A movable probe needle which projects above the mercury pool, measures the fields within the waveguide. The research includes the calculation of parameters governing voltage breakdown due to the presence of mercury vapor the comparison of voltage standing wave ratio measurements obtained from a slotted waveguide with the measurements obtained from the mercury waveguide transverse electric field measurements obtained by moving the probe across the broad wall of the mercury waveguide at the fundamental, second, and third harmonics the development of a multimode launcher and the development of a multimode load.
