Two questions about microwave ovens

any one plesae has an idea about the following question related to microwave oven


1-does a microwave excite a signal mode or multiple mode, and why is this prefered?


2-explain mode stirring and how it is implemented in microwave ovens?

note that the microwave oven excited at 25 GHZ

Are you sure about the 25 GHz? It is my understaning that in the USA the frequency is closer to 2.4 GHz.

I am curious now and will poke around to check the number.
