A cluster of many small holes with negative imaginary surface impedances may generate a negative refraction index

Ahmed Alsaedi, Bashir Ahmed, Durga Prasad Challa +2

We deal with the scattering of an acoustic medium modeled by an index of refraction $n$ varying in a bounded region $Ω$ of $R^{3}$ and equal to unity outside $Ω$ . This regio…

Extraction of the index of refraction by embedding multiple and close small inclusions

Ahmed Alsaedi, Faris Alzahrani, Durga Prasad Challa +2

We deal with the problem of reconstructing material coefficients from the farfields they generate. By embedding small (single) inclusions to these media, located at points $z$ in t…

The equivalent medium for the elastic scattering by many small rigid bodies and applications

Fadhel Al-Musallam, Durga Prasad Challa, Mourad Sini

We deal with the elastic scattering by a large number $M$ of rigid bodies, $D_{m} := ε B_{m} + z_{m}$ , of arbitrary shapes with $0 < ε << 1$ and with constant Lamé coefficients…

Multiscale analysis of the acoustic scattering by many scatterers of impedance type

Durga Prasad Challa, Mourad Sini

We are concerned with the acoustic scattering problem, at a frequency $κ$ , by many small obstacles of arbitrary shapes with impedance boundary condition. These scatterers are assum…
