Re: Inductive Coupling through a Steel Enclosure

Picture two hollow stell boxes each with a 20mm hole drilled in them at the
same location. The thickness of the steel is aprox. 5mm. The boxes are 9cm
cubed. The coils, facing each other, sit flush with the surface of the
steel. The boxes are aprox. 5mm apart.

What do you mean by a radial slot?

Yes, I'm trying not to disclose too much information to protect myself
and the company.

I have tried an aluminum shield around the coils with some success. I am
using a class E amplifier. I was trying to stay below 1 Mhz for FCC
reasons. I came across some literature that the FCC allows inductive
coupling in the 13 MHz region.

Is it possible to cut a thin radial slot in the steel and fill it with a
non conductive material?
