Transmission Spectrum of One-dimensional “Chirped”Photonic Crystals Containing Negative Refraction Materials
The "chirped" function is induced to the one dimensional photonic crystals containing negative index media. The transmission spectrum of this type photonic crystal is investigated using the transfer matrix method. The transmission spectrum
as a function of the incident angle and the frequency
is simulated using computing. The results indicate that this photonic crystal has a wider reflect band which is insensitive to the incident angle when the thickness is not much modulated by the "chirped" function. The reason is that the real part of the complete effective index is almost zero
but the imaginary part is more lager. This special property could be used to make high quality reflection lens with wide band and full incident angle.
