Abstract- This article studies the construction of a Super lens by an anisotropic triangular photonic crystal. The photonic bands and the contours of equi-frequency surfaces are studied by PWE method. This lens has an effective index of refraction of -1 for TM polarization, where the air holes relative radius are 0.35a and ω= 0.222(2πc/a). Propagation of electromagnetic waves through this Super lens and the construction of an image are also studied by means of FDTD method. Calculation shows that it is possible to have transmission rate more than 95% with a tailored adjustment of photonic crystal’s boundaries.
Keywords: Anisotropic Photonic Crystals, Negative Refraction, Super Lens, Optical Imaging Super-Resolution.
