Magnetostatic Spin Waves
i.e., that the free currents flow in closed loops. Likewise, the time derivative of the fourth Maxwell equation implies that Jfree has no time dependence in magnetostatics. Often, magnetostatics is taken to be the situation in which ∇ · Jfree = 0 and D, E and Jfree have no time dependence, without explicit assumption that B and H also have no time dependence. Discuss the possibility of waves of...

متن کاملMode dispersion in biperiodic photonic crystal waveguides
We propose and analyze biperiodic photonic crystal waveguides, where there are two sets of discrete translational symmetry along the propagation direction of the photonic crystal waveguides. We present a general method based on a spatial Fourier transform for the calculation of mode dispersion in such biperiodic waveguides. We demonstrate that by modifying the periodicity of only two rows of ai...
متن کاملInverse dispersion engineering in silicon waveguides
We present a numerical tool that searches an optimal cross-section geometry of silicon-on-insulator waveguides given a target dispersion profile. The approach is a gradient-based multidimensional method whose efficiency resides on the simultaneous calculation of the propagation constant derivatives with respect to all geometrical parameters of the structure by using the waveguide mode distribut...
متن کاملExact dispersion relation for nonlinear plasmonic waveguides
We derive an exact dispersion relation for the surface plasmon polaritons of a nonlinear plasmonic waveguide using exact field decomposition of TM waves. Our approach generalizes the known linear dispersion relations to the case of a medium nonlinearity of the form εNL = εL + α|E|2n. We apply the unique dispersion relation to a plasmonic waveguide with a Kerr-type nonlinearity (n = 1) and show ...
