A Multi-Frequency Tomographic Inverse Scattering Using Beam Basis Functions

Ram Tuvi • Sensors (2022)

We present an overview of a beam-based approach to ultra-wide band (UWB) tomographic inverse scattering, where beam-waves are used for local data-processing and local imaging, as an alternative to the conventional plane-wave and Green’s fun...

Green’s functions for geophysics: a review

Ernian Pan • Reports on Progress in Physics (2019)

The Green's function (GF) method, which makes use of GFs, is an important and elegant tool for solving a given boundary-value problem for the differential equation from a real engineering or physical field. Under a concentrated source, the ...

Investigation of dipole emission near a dielectric metasurface using a dual-tip scanning near-field optical microscope

Abbasirad Najmeh, Barreda Angela, Arslan Dennis, Steinert Michael et al. • Nanophotonics (2021)

A wide variety of near-field optical phenomena are described by the interaction of dipole radiation with a nanophotonic system. The electromagnetic field due to the dipole excitation is associated with the Green’s function. It is of great i...
