How do the blades disperse the microwaves?

The entire chamber is a resonant cavity. The entire space is inundated
with microwaves.

As a newcomer to this newsgroup, please allow me to clarify.

I do not mean to dispute your information about the stirrer blades, I
agree with you.

I am trying to get more information about what exactly is involved in
the dispersion. More than what I pick up off of the various "how does a
microwave oven work" hits that google returns.

Thank you,
