Boundary Element Methods (BEM) have emerged as a robust numerical technique for addressing wave propagation problems across diverse fields such as acoustics, elastodynamics, and electromagnetics.

Finite-Difference Time-Domain (FDTD) methods represent a cornerstone in the numerical simulation of wave propagation phenomena. These methods solve Maxwell’s equations directly in the time domain, ...

The coupled normal mode method is a powerful approach for solving range-dependent propagation problems in underwater acoustics. An important area of study is to improve stability and efficiency so as ...

SoftBank Corp. (“SoftBank”) and its subsidiary HAPSMobile Inc. (“HAPSMobile”) developed a new global model that can estimate radio wave interference at high altitudes and enable the design of network ...
