Microwave absorption of film explained accurately by wave cancellation theory

It has been proved previously that in the field of microwave absorption, film and material are confused, impedance matching theory (IM) which is usually applied to metal-backed inadequate. By analysis experimental data from a novel theoretical perspective, it elaborated here problems with IM cannot be solved even if different criteria such as value |Zin - Z0| or phase difference between Zin (input film) Z0 (Characteristic material) used therefore current theories related need replaced by wave cancellation theory. The this work applies published supports new against ones. conditions for minima reflection loss |RL| at large values have also determined transmission-line
