Abstract

We use the plane-wave (PW) method to calculate the superlens frequency of photonic crystals with various material compositions. At this frequency, photonic crystal behaves like a medium with isotropic negative index equal to −1. The relationship between the frequency and material compositions is derived from the calculated data. For the TE and TM modes, the relationship has the same format. From the relationship, a case has been chosen and, under these conditions, the wave-propagating field through the photonic crystal has been calculated by the finite-difference time-domain method. A good agreement is obtained between the results from the PW method and the finite-difference time-domain calculation. This is very useful for fabricating photonic crystal superlens material at an appropriate frequency.
