Prolate spheroidal wave functions (PSWFs) and their discrete counterparts – the discrete prolate spheroidal sequences (DPSSs) – have emerged as essential tools in the analysis of band‐limited ...

Electromagnetic wave propagation in layered media is a subject of enduring importance in both theoretical and applied physics. It encompasses the study of how electromagnetic fields interact with ...

In recent years, physicists have been trying to better understand the behavior of individual quantum particles as they move in space. Yet directly imaging these particles with high precision has so ...
