Global, explicit representations of nonlinearities are desirable when implementing nonlinear Wave Digital (WD) structures, as they free us from the burden of managing look-up tables, performing data ...

Three intertwined time directions may underpin everything, turning space into mere “paint on the canvas” and pushing physics toward a long-sought theory of everything.

We present an analysis of the perfectly matched layer in cylindrical coordinates discretized with a staggered second-order accurate finite difference time domain method. For fixed discretization ...
