Nonlinear wind‐wave effects in backscatter.

Dynamical effects of anisotropic inelastic scattering in electron backscatter diffraction.

We present a model which describes the appearance of excess and deficiency features in electron backscatter diffraction (EBSD) patterns and we show how to include this effect in many-beam dynamical simulations of EBSD. The excess and deficiency features appear naturally if we take into account the anisotropy of the internal source of inelastically scattered electrons which are subsequently scat...

Intermediate Wave Effects in Microwave Backscatter from the Ocean

Nonlinear Effects in Photocathodes

Recent experiments at the Stanford Linear Accelerator Center (SLAC) [l] have demonstrated that the photoemitted number of electrons from a cesium-activated gallium arsenide (GaAs) crystal saturates at high incident flux, becoming insensitive to the incident photon flux at high intensity. This article offers a physical model that attempts to explain this phenomenon. A comparison of experimental ...

Effects of rain on Ku-band backscatter from the ocean

[1] During the Kwajalein Experiment (KWAJEX) in July and August 1999, measurements of the normalized radar cross section of the ocean, so, were made at Ku-band with HH and VV polarizations from the R/V Ronald H. Brown. Data were collected at a variety of incidence angles during periods of rainfall as well as during clear conditions. During the experiment the rainfall rate ranged from 0 to 80 mm...

FM Backscatter

This paper enables connectivity on everyday objects by transforming them into FM radio stations. To do this, we show for the first time that ambient FM radio signals can be used as a signal source for backscatter communication. Our design creates backscatter transmissions that can be decoded on any FM receiver including those in cars and smartphones. This enables us to achieve a previously infe...
