Microwave electrothermal thruster, also known as MET, is a propulsion device that converts microwave energy [1] (a type of electromagnetic radiation) into thermal (or heat) energy. These thrusters are predominantly used in spacecraft propulsion , more specifically to adjust the spacecraft’s position and orbit.
The FDA accepts that microwaves can be used to heat food for commercial use, pasteurization and sterilization. [4] The main mechanism of microbial inactivation by microwaves is due to thermal effect; the phenomenon of lethality due to 'non-thermal effect' is controversial, and the mechanisms suggested include selective heating of micro-organisms, electroporation, cell membrane rupture, and ...
An industrial microwave tunnel oven for heating plastic parts prior to extrusion. Microwave heating, as distinct from RF heating, is a sub-category of dielectric heating at frequencies above 100 MHz, where an electromagnetic wave can be launched from a small dimension emitter and guided through space to the target.

[1] [2] The authors presented a platform for integrating all the components of a microwave circuit inside a single substrate, with a rectangular cross-section. Using a single substrate guarantees a limited volume and a simplicity of manufacture, while the rectangular cross-section of the line provides the advantages of the waveguide topology in ...
It offered instructions for heating in the oven, but in the name of fairness, I used the microwave to keep the playing field level. Once out of the microwave and the packaging, the sandwich ...
