The new laser phenomenon has some interesting features. For instance, in a conventional laser relying on low-momentum electrons, electrons often reabsorb the emitted photons, and this reduces overall efficiency.

Comparing the values of cloaking and resonance frequencies, it is seen that the values are interleaved with each other: it may be shown that in general, when passive materials are employed, there is always a resonant peak between two neighboring cloaking frequencies, and vice ver …
