In this paper, the problem of simultaneous wavelet estimation and deconvolution is investigated with a Bayesian approach under the assumption that the reflectivity obeys a Bernoulli-Gaussian distribution. Unknown quantities, including the seismic wavelet, the reflection sequence, and the statistical parameters of reflection sequence and noise are all(More)
In this paper, the transmission-line (TL) metamaterials (MTMs) are used to implement Mu-Near-Zero (MNZ) medium with one component of the permeability tensor approaching zero. The tensor TL unit cells are utilized to realize MNZ media with anisotropic medium parameters, whereas the background medium is composed by elements with isotropic medium parameters.(More)
