Light scattering from stationary -symmetric collections of particles
Olga Korotkova, Paulo A. Brandão
A potential scattering theory from deterministic and random collections of particles with gain and loss is introduced and the forms of their structure and pair-struc…
Scattering theory for stationary materials with symmetry
Paulo Brandão, Olga Korotkova
A theoretical framework is developed for scattering of scalar radiation from stationary, three-dimensional media with correlation functions of scattering potentials obeying $\mathc…
Low coherence-induced resonance in double-layer structures having parity-time symmetry
Paulo A. Brandão, João P. Mendonça, S. B. Cavalcanti
We derive simple formulae for the transmittance and reflectance of Gaussian-Schell beams incident upon any stratified dielectric structure by using second-order classical c…
Non-Hermitian spectral changes in the scattering of partially coherent radiation by periodic structures
Paulo A. Brandão, S. B. Cavalcanti
The physical aspects of partially coherent radiation interacting with deterministic non-Hermitian periodic materials remain largely unexplored in the statistical optics literature.…
Scattering of partially coherent radiation by non-Hermitian localized structures having Parity-Time symmetry
Paulo. A. Brandão, Solange B. Cavalcanti
A theoretical model based on two-point scatterers is suggested to investigate scattering of partially coherent radiation by a non-Hermitian localized structure, invariant under the…
Stability boundaries of a Mathieu equation having PT symmetry
Paulo A. Brandão
I have applied multiple-scale perturbation theory to a generalized complex -symmetric Mathieu equation in order to find the stability boundaries between bounded and unbounded s…
