Abstract: The ability to completely absorb an electromagnetic wave by a material with a thickness much smaller than the resonant wavelength is an essential requirement for micro-miniature, flexible and lightweight electromagnetic wave devices. The present inventors combine a metal layer array with an inverse cross metal antenna through a dielectric separator and place a reflector at the bottom, to demonstrate a perfect absorber of metamaterial electromagnetic waves, especially microwaves, as thin as 1/1250 of the target wavelength. Compared to the conventional three-layer absorber, the modified design of the present application reconfigures a path of an induced current without changing a patch and a dielectric layer, thereby reversing the direction of a dipole magnetic field and significantly increasing the magnetic flux, to reduce a resonant frequency by a factor of up to 10. The ultra-thin film electromagnetic wave absorber of the present application includes a stack together with the reflector to realize the full absorption under critical coupling conditions, and the critical coupling condition is identified by monitoring the reflection phase shift across the resonant frequency. The present invention provides guidance for further reducing the thickness, and the present invention can be extended to other frequencies.
