Electromagnetic energy within single-resonance chiral metamaterial spheres
Tiago J. Arruda, Felipe A. Pinheiro, Alexandre S. Martinez
We derive an exact expression for the time-averaged electromagnetic energy inside a chiral dispersive sphere irradiated by a plane wave. The dispersion relations correspond to a ch…
Unconventional Fano effect and off-resonance field enhancement in plasmonic coated spheres
Tiago J. Arruda, Alexandre S. Martinez, Felipe A. Pinheiro
We investigate light scattering by coated spheres composed of a dispersive plasmonic core and a dielectric shell. By writing the absorption cross-section in terms of the internal e…
Boundary element method and simulated annealing algorithm applied to electrical impedance tomography image reconstruction
Olavo Henrique Menin, Vanessa Rolnik, Alexandre Souto Martinez
Physics has played a fundamental role in medicine sciences, specially in imaging diagnostic. Currently, image reconstruction techniques are already taught in Physics courses and th…
