Boundary integral equations (BIEs) have emerged as a powerful framework for modelling wave propagation, particularly in problems defined over unbounded or complex domains.

This letter is devoted to applying the higher order finite-difference approximations to the tropospheric radio-wave propagation problem. It is proposed to use the fourth-order approximation (Numerov ...

Wave propagation at the bottom of the electromagnetic spectrum (below 300 kHz) in the Earth-ionosphere waveguide system has been an interesting and important area of investigation for the last four ...

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre ...

Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether ...
