Epsilon-negative (ENG) and mu-negative (MNG) materials are successfully realized by using composite right/left-handed transmission line (CRLH TL), based on which the photonic crystals were also constituted. The simulated and measured scattering parameters and phase shift indicate that the...

We consider an inverse quadratic programming (QP) problem in which the parameters in both the objective function and the constraint set of a given QP problem need to be adjusted as little as possible so that a known feasible solution becomes the optimal one. We formulate this problem as a linear...

With the large-scale development of shale gas, oil-based drilling fluids are widely used, generating significant amounts of solid wastes from oil-based shale drilling cutting (OBSDC), which are difficult to degrade and biologically toxic. The current treatment methods do not meet the...
