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…
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…
Nonparaxial electromagnetic Bragg scattering in periodic media with PT symmetry
P. A. Brandão, J. H. Nascimento. S. B. Cavalcanti
The evolution of a pair of resonant Bragg modes through a medium characterized by a complex one-dimensional -symmetric periodic permittivity is thoroughly investigate…
Bragg-induced power oscillations in PT symmetric periodic photonic structures
Paulo A. Brandão, Solange B. Cavalcanti
We study Bragg-induced power oscillations in Fourier space between a pair of optical resonant transverse modes propagating through a periodic PT symmetric lattice, represented by a…
