High frequency (over 400 hertz) electromagnetic devices 1

[mtrguy]

I am attempting to form a list of high frequency (over 400 hertz) electromagnetic devices.
Anybody have a device in mind?

Thanks,

Suggestion: Please, would you be more specific since there are many over 400Hz devices, e.g.
Electronics-transmitters, receivers, radars, transponders, computers, printers, VCRS, etc.
Power-Induction ovens, microwaves, converters, motors, transformers, cables, generators, medical devices, etc.
Controls-Modulators, demodulators, multiplexers, etc.
Instrumentation-sensors, telemetry, motion sensors, proximity sensor, level sensors, etc.
Etc.

Specifically I am interested in any electromechanical applications were powdered iron parts could be used.

Thank you for the list could these devices use powdered metal in the magnetics?

It could potentially be used on or within all of the above posted equipment except circuitry consisting of chips, ASIC, and components not using it, e.g. capacitors, semiconductors, etc.
