Almost periodic solutions of retarded SICNNs with functional response on piecewise constant argument
Marat Akhmet, Mehmet Onur Fen, Mokhtar Kirane
We consider a new model for shunting inhibitory cellular neural networks, retarded functional differential equations with piecewise constant argument. The existence and exponential…
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 varying in a bounded region of and equal to unity outside . 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 in t…
