Determining the Effective Electromagnetic Parameters of Photonic Crystal by Phase Unwrapping and Denoising Method

Abstract EN

The electromagnetic parameters of the dispersion material and metamaterial are vital in the engineering.

The phase unwrapping method is proposed to deal with the phase ambiguity of the transmission and reflection method in electromagnetic (EM) parameters extraction.

The computed results demonstrate that the proposed method can give the correct effective parameters.

In dealing with scattering parameters with noise, the wavelet transform method is utilized to remove the noise added to the scattering parameters.

The simulated results show that the correct material parameters can be obtained by wavelet denoising method.

Finally, the proposed method is used to extract the parameters of the photonic crystal.

The effective parameter gives a different aspect in explanation to the function for the photonic crystal.
