Phase-change meta-photonics [PDF]
, 2016 We combine phase-change materials and metamaterial arrays (metasurfaces) to create new forms of dynamic, tuneable and reconfigurable photonic devices including ‘perfect’ absorbers, infra-red light modulators, optical beam steerers and enhanced phase ...

One-Dimensional Nonlinear Stefan Problems in Storm’s Materials
Mathematics, 2013 We consider two one-phase nonlinear one-dimensional Stefan problems for a semi-infinite material x > 0; with phase change temperature Tf : We assume that the heat capacity and the thermal conductivity satisfy a Storm’s condition. In the first case, we

A New Method for 3-Satisfiability Problem Phase Transition on Structural Entropy
IEEE Access, 2021 The phenomenon of phase transition is an important property of the satisfiability (SAT) problem. It not only determines the difficulty of solving the problem, but also plays an important role in designing fast solving algorithms.

A Steady State Phase Change Problem [PDF]
Mathematics of Computation, 1967 In a previous paper [4] the solution to the Stefan problem for a one-dimensional semi-infinite slab with constant boundary and initial conditions was shown to be given by the limit of solutions to a nonlinear parabolic equation for the "specific internal energy." In this paper we obtain the same result for the Stefan problem in a bounded two- or three ...
