By means of modification of the extended homoclinic test approach (mEHTA),we obtain some new exact soliton solutions for the (2+1)-dimensional Ablowitz-Kaup-New
In order to enhance transmittance in the long-wavelength infrared range, the major parameters of periodic sub-wavelength structures (SWS) with square holes on z
A technique of fiat crystal x-ray spectrometer for quantitative spectral measurement is described.For the flat crystal spectrograph geometry, the quantitative r
A general expression for the scalar susceptibility in QED3 is given.We adopt the Dyson-Schwinger equation for the fermion propagator to solve Xc within a range
