Abstract

The problem of imaging in a honeycomb lattice photonic crystal (PhC) slab is studied theoretically. Also, the superlens imaging of two sources separated by a distance less than a wavelength is shown. The finite-difference time-domain (FDTD) method is employed to investigate the unique feature of imaging of such PhC slab. Specially, it is shown that the surface termination is important for obtaining good imaging quality in honeycomb PhC slab..

Keywords
