Transmissivity estimates can be obtained by different approaches, mainly analytical and empirical. The application of methods requires checking non-linear well losses due to turbulence vertical flow related partial penetration. empirical approach relates transmissivity values specific capacity data measured in the same well. interpretation available pumping tests highlights porous media solutio...

We study the dynamics of an ultrafast single photon pulse in a one-dimensional waveguide two-point coupled with a Jaynes-Cummings system. We find that for any single photon input the transmissivity depends periodically on the separation between the two coupling points. For a pulse containing many plane wave components it is almost impossible to suppress transmission, especially when the width o...

Significant loss in transmissivity of the fiber used for the 18 years operations in JT-60U has been discovered: thereby making optimization of the filter configuration in the polychromator in Thomson scattering system for the high performance plasmas in JT-60SA is an essential task. The loss in the optical components induced by radiation from neutrons and γ-rays in particular needs to be examin...

The coherent dynamics of vibronic wave packets in the green fluorescent protein is reported. At room temperature the non-stationary dynamics following impulsive photoexcitation displays an oscillating optical transmissivity pattern with components at 67 fs (497 cm) and 59 fs (593 cm). Our results are complemented by ab initio calculations of the vibrational spectrum of the chromophore. This ana...

Systems with coupled cavities and waveguides have been demonstrated as optical switches and optical sensors. To optimize the functionalities of these optical devices, Fano resonance with asymmetric and steep spectral line shape has been used. We theoretically propose a coupled photonic crystal cavity-waveguide structure to achieve Fano resonance by placing partially reflecting elements in waveg...

The transmissivity within the photonic band gap of two-dimensional photonic crystals of macroporous silicon is reported as a function of crystal thickness. Measurements were carried out for crystals of nominally 1, 2, 3, and 4 crystal layers using a commercial parametric source, with a wavelength tunable from 3 to 5 mm. For wavelengths well within the 3–5 mm photonic band gap, attenuation of ap...

A multiwavelength erbium-doped fiber (EDF) laser based on a nonlinear amplifying loop mirror (NALM) is proposed and experimentally demonstrated. The NALM provides intensity-dependent transmissivity to equalize different-wavelength powers and the transmission can be uniquely optimized by controlling the cavity loss associated with a section of un-pumped EDF, which also enhances the output signal...

Estimating subsurface hydraulic properties using the groundwater (GW) response to Earth tides (ET) and atmospheric pressure is an alternative approach pumping or slug tests (passive vs. active methods). Yet testing applicability of models under different conditions comparing results with traditional methods are lacking. We first review assumptions analytical used evaluate GW ET their in unconfi...
