Abstract: A metallic-dielectric photonic crystal is formed with a periodic structure defining a plurality of resonant cavities to selectively absorb incident radiation. A metal layer is deposited on the inner surfaces of the resonant cavities and a dielectric material fills inside the resonant cavities. This photonic crystal can be used to selectively absorb broadband solar radiation and then reemit absorbed radiation in a wavelength band that matches the absorption band of a photovoltaic cell. The photonic crystal can be fabricated by patterning a sacrificial layer with a plurality of holes, into which is deposited a supporting material. Removing the rest of the sacrificial layer creates a supporting structure, on which a layer of metal is deposited to define resonant cavities. A dielectric material then fills the cavities to form the photonic crystal.

Abstract: A method and apparatus for extended access barring (EAB) in a wireless communication system. In the proposed method, EAB application information is defined. Further, a base station is configured to send random access (RA) response within RA response window if it receives any random access preamble, so RA response window should be set as the minimum time duration UE should check the existence of RA response. In the proposed method, the UE configured with EAB should wait the duration of RA response window to receive RA response before skipping initial EAB checking. If RA response window passed and no RA response received, UE skips EAB checking in case of initial random access preamble transmission.
