In a de-icing system for preventing the formation of ice on, or for de-icing, icing-prone areas of an airplane, the icing-prone areas include dielectric composite structural materials, which are highly permeable for electromagnetic waves, and at least two microwave sources are provided and connected to microwave uncoupling areas disposed adjacent the icing-prone areas, and the microwave sources are interconnected by redundant switchable microwave guides permitting bridging of a microwave source in case of failure of such microwave source.

Microwave de-icing system for aircrafts

In an apparatus for the selective heating of foods disposed on a serving tray to serving temperature by means of a microwave oven having a gyrotron as a heat source, individual guide means are provided for guiding the microwave radiation individually to particular dishes on the tray and a control computer controls the radiation of, and the heat generated in, the dishes during passages of the tray with the dishes through the microwave oven.
