Microwave generator and processes thereof

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.
