An electronic system of infrared spectral data for toxicological analysis.
Abstract A large number of non-volatile poisons have been analyzed by infrared spectroscopy and spectral indices have been stored as standards. Comparison of the spectra of unknown samples with the standard spectra allows identification of the unknown samples. This comparison is carried out by computer.
A simple rapid identification of psychotropic drugs by infrared spectrophotometry in emergency--preliminary description.
Abstract A large number of pharmaceutical products has been analysed by this original method. It is based on the extraction with chloroform of the active principles followed by infrared absorption spectrometry. Comparison of the spectra obtained with those for compounds previously obtained allows the prompt identification of unknown samples.
Integrated two-beam antenna array featuring dual-circular polarization
A concept of an integrated antenna array featuring two independent beams and dual circular polarization has been described. The antenna array consists of two radiating elements which are excited at two orthogonally placed feeding ports with the use of four appropriately connected 3-dB/90° directional couplers. Therefore, such an array generates two symmetrically located beams having right-handed circular polarization (RHCP) and identical two beams having left-handed circular polarization (LHCP). The presented concept has been verified by the design and measurements of an antenna array operating at 2.4 GHz frequency range.
