Exact Local-Field Renormalization for Deep-Subwavelength Particles in Rectangular Cavities
Koffi-Emmanuel Sadzi, Yakir Hadad
We present a rigorous, semi-analytical framework for predicting the eigenfrequencies of a deep-subwavelength particle embedded in a perfectly conducting rectangular cavity. The for…

Loss vs Magnetization Threshold Phenomenon for Lorentz Nonreciprocity Induced by a Gyrotropic Particle Inside a Cavity
Koffi-Emmanuel Sadzi, Yakir Hadad
When a plasmonic particle is subject to a static magnetic field, , its gyrotropic response gives rise to nonreciprocal dynamics of the entire ambient su…

Universal radiation dynamics by temporal transitions in optical waveguides
Amir Shlivinski, Yakir Hadad
When an excited electromagnetically open optical waveguide goes through a temporal transition of its material properties, it radiates to the ambient surroundings. In this letter, w…
