  • Patent number: 3983356
    Abstract: An end load for a microwave oven for efficiently attenuating microwave energy escaping from an oven access port. The end load has a circular configuration and consists of an inner cylindrical member and a concentrically mounted, outer conductive member. The members are spaced apart to provide a tuned annular volume through a lossy liquid, such as water, is passed. The inner member is made of a microwave lossy material having a dielectric constant that optimumly matches the energy transfer from air to water and has a wall thickness that is also tuned to trap microwave energy. The outer member is made of a conductive material that provides an inwardly reflective surface for confining the microwave energy.
