A coherence-controlled holographic microscope (CCHM) enables quantitative phase imaging with coherent as well as incoherent illumination. The low spatially coherent light induces a coherence gating effect, which makes observation of samples possible also through scattering media. The paper describes theoretically and simulates numerically imaging of a two-dimensional object through a static sca...

The scattering of waves by a buried object is often obscured by the clutter around it. Such clutter can be attributed to the scattering by random rough surfaces and random discrete scatterers. Recent studies show that, because of the memory effect, the angular correlation function can suppress the effects of clutter and make the scattering by the buried object more conspicuous. In this paper, w...

Ultrafast relaxation dynamics of electrons at dielectric-metal interfaces reflect the nature of the electronic interaction with both the substrate and the adsorbed layer. The full understanding of macroscopic electrical transport properties across an interface requires the knowledge of the energies, spatial extent of the interfacial electronic states, and the electron scattering length. With th...

Current techniques for rendering multilayered translucent materials such as skin, marble, jade, and paper can achieve startling realism by modeling subsurface scattering. However, due to performance concerns, all of these techniques require fixing the material properties, including the depth and scattering parameters of each layer, before rendering begins. This makes it impractical to calculate...

We derive a semi-analytic solution for the structure of conduction-mediated transition layers above an X-ray illuminated accretion disk, and calculate explicitly the X-ray line radiation resulting from both resonance line scattering and radiative recombination in these layers. The vertical thermal structure of the illuminated disk is found to depend on the illuminating continuum: for a hard pow...

1. ABSTRACT In this paper, we present forward model of the microwave backscattering from a vegetated terrain at L band for application in the upcoming SMAP (Snow Moisture Active and Passive) mission. The objective of the SMAP mission is to provide global measurements of soil moisture and its freeze/thaw state [1]. These measurements will be used to enhance understanding of processes that link t...

This study presents a theoretical investigation of the effect of the aerosol vertical distribution on the aerosol radiative effect (ARE). Four aerosol composition models (dust, polluted dust, pollution and pure scattering aerosols) with varying aerosol vertical profiles are incorporated into a radiative transfer model. The simulations show interesting spectral dependence of the ARE on the aeros...

We report the strong screening of the remote charge scattering sites from the oxide/semiconductor interface of buried enhancement-mode undoped Si two-dimensional electron gases (2DEGs), by introducing a tunable shielding electron layer between the 2DEG and the scattering sites. When a high density of electrons in the buried silicon quantum well exists, the tunneling of electrons from the buried...

We present a set of universal relations which relate the local transmission, reflection, and polarization conversion coefficients of a general class of non-magnetic passive ultrathin metasurfaces. We show that these relations are a result of equal forward and backward scattering by single layer ultrathin metasurfaces, and they lead to confinement of the transmission, reflection, and polarizatio...
