We demonstrate measurement of material optical parameters, in the THz regime, by mounting the sample under test on a spinning wheel. The proposed measurement technique is implemented using double-modulated terahertz differential timedomain spectroscopy (double-modulated THz-DTDS). Spinning sample addresses fundamental limitations imposed by linear sample dithering. The concept of spinning the sample...
We present our preliminary results on the detection of antigen-antibody complexes using terahertz spectroscopy. Our study indicates that a difference between the absorption spectra of pure antibody/antigen and the antibody-antigen complex may be useful for biomedical applications. Furthermore, we introduce a new carrier material, which has several advantages over previously used materials, such as...
In the following paper we present a complete analytical model that predicts the band-gap (Eg) of single-walled carbon nanotubes (SWCNTs) directly from their diameter (d) and chiral angle (thetas). The proposed analytical model is based on two mathematical expressions that have been derived by curve-fitting the outcome generated from the third-nearest-neighbor tight-binding (TB) method in conjunction...
