“…As our cylindrical-grid finite-difference time-domain results show, the incident pulse is well absorbed with very low backscatter. Akin to the performance of other types of cylindrical PPML media however [30], the subsections of the pulsed incident wavefront that (locally) are near grazing incidence to the cylindrical PPML-vacuum interface are not as effectively absorbed as compared to the wavefront subsections that (locally) are near normal incidence. Finally we remark that, from the symmetry in the material tensors (c.f.…”

We demonstrate the existence of metamaterial blueprints describing, and fundamental limitations concerning, perfectly reflectionless omnidirectional electromagnetic absorbers (PR-OEMA). Previous attempts to define PR-OEMA blueprints have led to active (gain), rather than passive, media. We explain this fact and unveil new, distinct limitations of true PR-OEMA devices, including the appearance of an "electromagnetic horizon" on physical solutions. As practical alternatives we introduce alternative OEMA blueprints corresponding to media that, while not reflectionless, are nonetheless effective in absorbing incident waves in a manner robust to incident wave diversity.
