The angular absorber based on one-dimensional Photonic Crystal（PC）has been proposed and investigated.The absorber consists of multiple one dimensional PC

which has different periodicities.Both the real part and the imaginary part of the wave vector of the absorber will only have solutions at the Brewster angleby tailoring the overlap of the band gaps of these multiple one-dimensional PC.The absorber exhibits angular selectivity（the Brewster angle）in absorption within a broad waveband from 380 nm to 700nm（the visible wavelengths）under p-polarized illumination.It is also noted thatthe angular width in absorption is less than 5°.The simulation results show that the angular absorbance is above 99%

i.e.

perfect absorptionhas been achieved

when the incident lights illuminate on the absorber with the incident angle equalingto the Brewster angle.This feature of absorbing lights in a certain direction may have the potential in some new applications

such as solar thermophotovoltaic systems.
