Abstract
There is disclosed a microwave heating apparatus which includes a source of high frequency electromagnetic energy which generates microwaves having a predetermined operating wave length, a heating chamber to accommodate therein a material to be heated, a spatial arrangement to transmit microwaves generated by the source, and a surface wave transmission circuit or line positioned between the chamber and the spatial arrangement. The microwave power from the source is coupled to the spatial arrangement and possibly to the chamber. Heating of a material to be heated takes place as the high frequency electromagnetic waves impinge upon the material and penetrate thereinto.
