Scientists propose home made black hole
Apparently the first experimental demonstration of electromagnetic black hole in the microwave frequencies. The proposed black hole is composed of non-resonant and resonant metamaterial structures, which can absorb electromagnetic waves efficiently coming from all directions due to the local control of electromagnetic fields. Hence the electromagnetic black hole could be used as the thermal emitting source and to harvest the solar light.
