Optical imaging beyond the diffraction limit, ie, optical superresolution, has been studied
extensively in various contexts. This paper presents an overview of some mathematical …

We analyze spin and orbital angular momenta in monochromatic acoustic wave fields in a
homogeneous medium. Despite being purely longitudinal (curl-free), inhomogeneous …

Quantum teleportation faces increasingly demanding requirements for transmitting large or
even entangled systems. However, knowledge of the state to be transmitted eases its …

Diffraction is a natural phenomenon, which occurs when waves propagate or encounter an
obstacle. Diffraction is also a fundamental aspect of modern optics: all imaging systems are …

Efficient calculation of the light diffraction in free space is of great significance for tracing
electromagnetic field propagation and predicting the performance of optical systems such as …

In semiconductor and data storage device manufacturing, it is desirable to produce feature
sizes less than 30 nm with a high depth-to-width aspect ratio on the target material rapidly at …

We present a class of exact nonstationary solutions of Maxwell equations in vacuum from
dipole pulse theory: electric and magnetic dipole pulses. These solutions can provide for a …

A novel method is proposed to generate vector beams with arbitrary spatial variation of
phase and linear polarization at the nanoscale using compact plasmonic metasurfaces with …

We propose a method for generating focal beams with special intensity distributions using
radially polarized vortex beams in a 4Pi configuration. A spherical dark-hollow beam and …

Microscopic techniques based on nonlinear optical processes provide alternative ways to
visualize natural and artificial nanoscopic systems with minimum disturbance. In such …
