Recently, scientists in China experimentally realized a class of three-dimensional spatiotemporal wavepackets with spherical ...

Solutions of the electromagnetic wave equation are derived in systems containing spherical interfaces when the source field is that of a magnetic or electric point dipole. Piecewise constant ...

How do you teach Schrödinger’s equation to a 15 year old? This question was originally answered on Quora by Brian Bi.

We develop a theory of difference approximations to absorbing boundary conditions for the scalar wave equation in several space dimensions. This generalizes the work of the author described in [8].
