Wave Propagation in Pure-Time Modulated Step Media With Applications to Temporal-Aiming
Mourad Sini, Haibing Wang, Qingyun Yao
We analyze the propagation of an incident electromagnetic wave in a purely-time modulated medium. Precisely, we assume that the permeability is unchanged while the permittivity has…

Analysis of the acoustic waves reflected by a cluster of small holes in the time-domain and the equivalent mass density
Mourad Sini, Haibing Wang, Qingyun Yao
We study the time-domain acoustic scattering problem by a cluster of small holes (i.e. sound-soft obstacles). Based on the retarded boundary integral equation method, we derive the…
