Path Integral by Space-time Slicing Approximation In Open Bosonic String Field
Am-Gil Ri, Tae-Song Kim, Chol-Man Ri +1
In our paper, we considered how to apply the traditional Feynman path integral to string field. By constructing the complete set in Fock space of non-relativistic and relativistic…
Classical Equation of Electromagnetic Field in the Higgs Boson Field and Estimation on the Static Electrical Polarizability of Leptons
Il-Gwang Kim, Tae-Song Kim, Chol-Man Ri +1
In our paper we derived the classical motion equation of electromagnetic field in space with Higgs field and by means of it discussed the distributions of charge and current formed…
Mechanism of the Fano resonance in a planar metamaterials: Analysis from the coupled two-oscillator model
Song-Kum Song, Song-Jin Im
Mechanism of the Fano resonances in planar metamaterials demonstrate based on the coupled two-oscillator model. We have described the optical spectrums like reflectance and transmi…
Experimental study on the influence of binders on plastic deformation during sintering of cubic boron nitride powder under high pressure and high temperature
Su-Gon Kim, Gwang-Il Jon, Song-Jin Im
In this work, sintered polycrystalline cubic boron nitride (cBN) compacts, with titanium carbonitride (TiC0.7N0.3) and titanium nitride (TiN), respectively, as binders, were prepar…
Suppression of DC term in Fresnel digital holography by sequence subtraction of holograms
Jong-Chol Kang, Chol-Su Kim, Song-Jin Im
An experimental method for suppression of DC term in the reconstructed images from Fresnel digital holograms is presented. In this method, two holograms for the same object are cap…
Study on the Thickness Change of Nickel-Plated Layer in Fabrication of the Silver Hollow Nickel Waveguides by the Outer-Coating Method of the Liquid Phase Process
Sok-Bong Ro, Song-Jin Im, Uo-Hyon Kim
A metallic hollow waveguide is promising fiber for the delivery of laser radiation. Thickness of the nickel plated layer for supporting of the waveguide in fabrication of a dielect…
