Porous structures of shales are reconstructed using the markov chain monte carlo (MCMC) method based on scanning electron microscopy (SEM) images of shale samples from Sichuan Basin, China. Characterization analysis of the reconstructed shales is performed, including porosity, pore size distribution, specific surface area and pore connectivity. The lattice(More)
A 2D pyramidal metamaterial-based nano-structure is proposed as a wavelength-selective Thermophotovoltaic (TPV) emitter. Rigorous coupled-wave analysis complemented with normal field method is used to predict the emittance as well as the electromagnetic field and Poynting vector distributions. The proposed emitter is shown to be wavelength-selective,(More)
