Light switching based on half space invisible states
A. R. Bekirov, A. F. Uspenskiy, V. A. Sitnyansky +2
We investigate a method for controlling light scattering based on the excitation of non-radiating states in a half-space through a tailored choice of incident radiation. For a fixe…
Resolution Limit in Microsphere-Assisted Super-Resolution Microscopy
Arlen R. Bekirov, Zengbo Wang, N. A. Lystseva +2
Visualization in the virtual image formed by dielectric microparticles has been shown to enable the distinction of objects that remain indistinguishable under direct observation. W…
Rotation effect in optical imaging of symmetrical figures in an opaque screen
A. Bekirov, V. Sitnyansky, S. Senotrusova +3
A novel effect of rotation in the optical image of structures in an opaque screen is presented. Theoretical calculations and experimental validation are presented. The features and…
Dielectric microparticles for enhanced optical imaging: a FDTD analysis of contrast and resolution
Arlen Bekirov, Zengbo Wang, Boris Lukyanchuk
This paper presents a comprehensive numerical analysis of super-resolution imaging using dielectric microparticles, employing the Finite-Difference Time-Domain (FDTD) method to elu…
