I'm trying to gather information about what types of magnetic material are most economical for a large flat LC resonator, 18 inches by 18 inches by somewhere between 1 to 3 inches high. I need 18x18 flat sheets of magnetic material on top and bottom that route flux to a center magnetic material with low losses between 50KHz and 200KHz. (plus more on 4 outer sides)
For example I could use 1 inch thick sheets of ferrite like 3C95 that can handle .125T with low losses.

The flux would increase in some other type material in the center section.
or
18x18 inch sheets of 0.5 inch thick material that can handle .25T with low losses.
or
18x18 inch of 0.25 inch thick material that can handle 0.5T with low losses, like some kind of laminated assembly of amorphous nanocrystaline thin metal sheets?
or
18x18 inch of 0.125 inch thick material that can handle 1T with low losses.
or
18x18 inch of 0.0625 inch thick material that can handle 2T with low losses, if it even exists.
I want to use thinner material to keep the size and weight down but maybe it cost too much more.
Is the cost of raw materials and fabrication of laminates in thin sheets more than the cost of using thicker ferrites?
How would laminates be done in thin sheets like that?
Does anyone have some recommendations on cheap materials and fabrication methods?
