The finite size effect on resonance poles
Friends Ndangali
The effect of the finite size of an array of scatterers on the position of the resonance poles of the scattered amplitudes is studied. This effect must be studied because in realit…

Electromagnetic Siegert states for periodic dielectric structures
Friends R. Ndangali, Sergei V. Shabanov
The formalism of Siegert states to describe the resonant scattering in quantum theory is extended to the resonant scattering of electromagnetic waves on periodic dielectric arrays.…

The resonant nonlinear scattering theory with bound states in the radiation continuum and the second harmonic generation
Friends Remy Ndangali, Sergei V. Shabanov
A nonlinear electromagnetic scattering problem is studied in the presence of bound states in the radiation continuum. It is shown that the solution is not analytic in the nonlinear…
