Patent ID: 8410859

Claim:
A microwave generator, comprising: a plurality of connected sequential sections in cascade including a first section and an output section, each of the plurality of connected sections including: a. an intermediate conductor; b. an upper conductor; c. a lower conductor; d. a first isolating material having a first thickness connected between the intermediate conductor and the upper conductor; e. a second isolating material having a second thickness connected between the intermediate conductor and the lower conductor; and f. a switch connected between the intermediate conductor and one of the following: i. the upper conductor, the first thickness being a switched thickness and the second thickness being an unswitched thickness; and ii. the lower conductor, the second thickness being a switched thickness and the first thickness being an unswitched thickness; and wherein: g. the unswitched thickness of the output section is larger than the unswitched thickness of the first section; and h. the increase in unswitched thickness from the first section to the output section comprises a monotonic increase.
