This paper describes a SAR measurement system for a 3G mobile phone (1718.5 MHz) using brain phantom material in a Perspex box sized to a small rat volume, with induced fields measured at multiple locations. SAR was computed from induced-field measurements and also estimated experimentally via temperature rise, with…

This engineering study investigates resonance behavior in diabolo metal bar optical antennas using FDTD numerical simulations and a dipole oscillator model. It reports that narrowing the antenna waist increases optical absorption and near-field enhancement at resonance and produces a red-shift in resonant…

This physics study reports ultranarrow optical absorption and two-phonon excitation spectroscopy of Cu2O paraexcitons in a high magnetic field at 1.2 K. A magnetic field enabled observation of an otherwise forbidden paraexciton absorption line and allowed measurement of field-dependent oscillator strength and energy…
