Electromagnetic scattering from relativistic bound states [PDF]

open access: yesPhysical Review C, 1993
The quasipotential formalism for elastic scattering from relativistic bound states is formulated based on the instant constraint in the Breit frame. The quasipotential electromagnetic current is derived from Mandelstam's five-point kernel and obeys a two-body Ward identity.

Spatial-Variant SAR Range Cell Migration Correction Using Subaperture Strategy

open access: yesSensors, 2021
The coupling between range and azimuth dimensions is the main obstacle for highly squinted synthetic aperture radar (SAR) data focusing. Range walk correction (RWC) processing is effective to remove the linear coupling term, but the residual high order ...

Robustness of the Fractal Regime for the Multiple-Scattering Structure Factor

open access: yes, 2016
In the single-scattering theory of electromagnetic radiation, the {\it fractal regime} is a definite range in the photon momentum-transfer $q$, which is characterized by the scaling-law behavior of the structure factor: $S(q) \propto 1/q^{d_f}$.
