In this paper, we use two dimensional graded photonic crystal consisting of square lattice with elliptical cross-section for designing negative effective index structures. The propagation of electric and magnetic fields is calculated by the finite-difference time-domain method. For calculation of photonic band structure and equal frequency contours we have used plan wave expansion method. According to the results, change angles of elements with elliptical Cross-Section have significant impact on the resolution.
Keywords: Graded Photonic Crystal, Finite-Difference Time-Domain method, elliptical cross-section, equal frequency contour
