Sensitivity Analysis of Spectral Indices to Ozone Absorption Using Physical Simulations in a Forest Environment: Comparative Study between MODIS, SPOT VéGéTATION & AVHRR
Spectral Indices Ozone Absorption Using Physical Simulations
2015/7/29
Considering a forest cover (Balsam Fir with various densities) we analyze the sensitivity of several vegetation indices to
ozone absorption using physical simulations in the spectral bands of MODIS,...
Nonlinear sigma model for optical media with linear absorption or gain
Nonlinear sigma model optical media linear absorption gain Optics
2012/4/24
In the framework of the Keldysh technique, we formulate the nonlinear sigma model for disordered optical media with linear absorption or gain. The effective action for fluctuations of the matrix field...
Controlled absorption and all-optical diode action due to collisions of self-induced transparency solitons
Controlled absorption all-optical diode action collisions of self-induced transparency solitons Optics
2012/4/20
We study inelastic collisions of counter-propagating self-induced transparency solitons in a homogeneously broadened two-level medium. The energy of the pulse can be almost totally absorbed in the med...
Dipole-Quadrupole Theory of Surface Enhanced Infrared Absorption and Appearance of Forbidden Lines in the SEIRA Spectra of Symmetrical Molecules
Dipole-Quadrupole Theory Surface Enhanced Infrared Absorption and Appearance Forbidden Lines the SEIRA Spectra Symmetrical Molecules Optics
2012/4/20
The paper presents main aspects of the Dipole-Quadrupole theory of Surface Enhanced Infrared Absorption (SEIRA). It is pointed out the possibility of appearance of the lines, caused by totally symmetr...

Coherent single-photon absorption single emitters 1D nanophotonic waveguides Optics
2011/8/1
Abstract: We study the dynamics of single-photon absorption by a single emitter coupled to a one-dimensional waveguide that simultaneously provides channels for spontaneous emission decay and a channe...
We demonstrate that 100% light absorption can take place in a single patterned sheet of doped graphene. General analysis shows that a planar array of small lossy particles exhibits full absorption und...
Enhancement of absorption bistability by trapping light planar metamaterial
bistability light planar metamaterial
2011/9/5
We study the peculiarities of the absorption bistability which appears in a planar metamaterial composed of a 4-fold periodic array of two concentric metal rings placed on a substrate of saturate abso...
The importance of inter-site coherences in the x-ray absorption spectra of mixed-valent systems
inter-site coherences in the x-ray mixed-valent systems
2010/11/19
We study the importance of inter-site coherences and quantum interference effects in
the x-ray absorption spectroscopy (XAS) of mixed-valent systems. We demonstrate its importance,
first for a simpl...
Enhanced Two-Photon Absorption in a Hollow-Core Photonic Bandgap Fiber
Enhanced Two-Photon Absorption Hollow-Core Photonic Bandgap Fiber
2010/11/12
We show that two-photon absorption (TPA) in Rubidium atoms can be greatly enhanced by the use of a hollow-core photonic bandgap fiber. We investigate off-resonant, degenerate Doppler-free TPA on the ...
Measurement of the two-photon absorption cross-section of liquid argon with a time projection chamber
Measurement two-photon absorption cross-section of liquid argon with a time projection chamber
2011/1/6
This paper reports on laser induced multiphoton ionization at 266 nm of liquid Argon in a Time Projection Chamber (LAr TPC) detector. The electron signal produced by the laser beam is a formidable too...
Broadband magnetometry by infrared-absorption detection of diamond NV centers
Broadband magnetometry infrared-absorption detection
2010/10/27
We demonstrate magnetometry by detection of the spin state of high-density nitrogenvacancy
(NV) ensembles in diamond using optical absorption at 1042 nm. With this technique,
measurement contrast an...
We analyze optical soliton propagation in the presence of weak absorption lines with much narrower linewidths as compared to the soliton spectrum width using the novel perturbation analysis technique ...
Transmission measurement of photo-absorption cross section of aluminum in soft X-ray region of 50 to 250eV
synchrotron radiation soft-X-ray aluminum thin-film photo-absorption cross section
2009/8/13
The photo-absorption cross section of aluminum was obtained from the ratio of transmission of aluminum thin-films with different area densities from 50 to 250eV with synchrotron radiation monochromati...
