For the Kerker effect to occur, particles need to have electric and magnetic polarizabilities of the same strength. This, however, is very challenging to achieve, as magnetic optical resonances in small particles are relatively ...
Electromagnetic and optical nonlinear effects provide an important platform in a broad spectrum of technologies, including high harmonic generation, sum and difference frequency conversions, self-focusing, optical solitons, ...
