We explore the possibility of the existence of guiding modes generated by surface modes in a three-layer waveguide composed of anisotropic single-negative metamaterial. The conditions for generation of even or odd guiding modes are deduced in eight subcases of single-negative (SNG) metamaterials with a different combination of positive or negative components of permittivity and permeability tensors,...
This paper presents a novel adaptive method of image denoising based on the dual-tree complex wavelet transform (DT-CWT) and independent component analysis (ICA). This method extracts the high-frequency component of the image with the DT-CWT, then combining with the principle of ICA virtual observed noise channel denoise. It does not need a lot of observed image samples, and it is unnecessary to know...
