Penetration depth of a ion beam coupled with an EM wave

[coquelicot]

TL;DR

How does the penetration depth of a ion beam coupled with a EM microwave depend upon the frequency of the wave?

A Ion source is a device that allows creating ion beams (e.g. argon ions) and to project them outside the device, for example to be further processed by a particle accelerator, or to irradiate materials or biological tissues etc.
Now, suppose the ion beam is coupled with an EM wave, especially of microwave frequency, and irradiates a given material.
Said very simplistically, the ions will oscillate at the frequency of the wave as they penetrate the irradiated material.
Then it is natural to suspect that the penetration depth of the ions depends not only upon their velocity, but also upon the frequency of the carrying wave.
Is there something known about that? what work has been done in this domain? any reference?

The main energy loss mechanism for charged particles in matter is ionization of the matter. There are energy loss tables I used in the distant pass to compute charge particle energy loss in things like thin metal films etc. That said, I'd expect near to no influence on particle energy loss by any microwaves unless the microwaves themselves could ionize the mater. That's a lot of microwaves.

Thx for answering me. How is the energy loss related to the penetration depth (a formula? or a name for a formula in order I can google it?).
