Abstract

PURPOSE: To give an adjustment to the reflective attenuation quantity of the microwave featuring a fixed frequency into a desired scale by coating the coating material onto the sheet which is composed mainly to the powder of the ferromagnetic substance mixed up with the insulating organic high molecular compound.
CONSTITUTION: The mixture of the ferromagnetic powder of the ferrmagnetic substance, iron, nickel, cobalt, etc. and the insulating organic high molecular compound such as the polyester featuring a resistibility of more than 1013Ωcm is kneaded and then formed into a desired thickness through the extrusion molding machine or the like, thus obtaining a sheet. This sheet is then attached to the surface of the microwave reflector, and the coating material composed mainly of the powder of the ferromagnetic substance and the insulating organic high molecular compound with addition of the organic solvent such as toluene or the like is coated on the surface of the sheet to form a paint film. In this way, the reflective attenuation quantity of the microwave featuring a fixed frequency can be adjusted to a desired scale.
