We demonstrate that 100% absorption of unpolarized monochromatic light can be achieved in an opaque layered medium. Conditions have been found when both s and p polarizations of the obliquely incident radiation are totally absorbed at the same angle of incidence. The effect is due to simultaneous excitation of surface and guided modes, with the radiation energy inflow being exactly balanced by dissipation.
