Theoretical prediction of the source-detector separation distance suited to the application of the spatially resolved spectroscopy from the near-infrared attenuation data cube of tissues
Yong-Wu Ri, Sung-Hu Jong, Song-Jin Im
The modified Beer-Lambert law (MBL) and the spatially resolved spectroscopy are used to measure the tissue oxidation in muscles and brains by the continuous wave near-infrared spec…
Study on the Vibration Displacement Distribution of a Circular Ultrasonic Motor Stator
Chol-Su Ri, Myong-Jin Kim, Chol-Su Kim +1
In this paper is presented a theoretical consideration on the stator's displacement distribution, which is one of the most important problems in defining the structure of the circu…
Plasmonic amplification and suppression in nanowaveguide coupled to gain-assisted high-quality plasmon resonances
Song-Jin Im, Gum-Song Ho
We theoretically study transmission in nanowaveguide coupled to high-quality plasmon resonances for which the metal loss is overcompensated by gain. The on-resonance transmission c…
All-optical control in metal nanocomposites due to a reversible transition between the local-field-enhancement and a local-field-depression upon irradiation by ultrashort control-pulses of light
Song-Jin Im, Gum-Song Ho
We theoretically study on non-perturbative effective nonlinear responses of metal nanocomposites based on the intrinsic third-order nonlinear response of metal nanoparticles. The l…
