Calculating spatiotemporally modulated surfaces: a dynamical differential formalism
Daigo Oue, Kun Ding, J. B. Pendry
Electromagnetic waves in a system with a space and time dependent boundary experience both diffraction and Doppler-like frequency conversion. In order to analyse such situations, c…
Electromagnetism at finite temperature: a density operator approach
Daigo Oue
In order to analyse classical electromagnetism in a medium at finite temperature we introduce `an optical density operator', and reformulate Maxwell's equations with the operator,…
Dissipation Effect on Optical Force and Torque near Interfaces
Daigo Oue
The Fresnel-Snell law, which is one of the fundamental laws in optics and gives insights on the behaviour of light at interfaces, is violated if there exists dissipation in the tra…
Complex-angle analysis of electromagnetic waves on interfaces
Daigo Oue
Electromagnetic wave is reflected and refracted at interfaces, satisfying Fresnel-Snell law which is required by conservations of energy and momentum. If the incident angle is lowe…
