The impact of hydration changes in fresh bio-tissue on THz spectroscopic measurements.
We present a study of how residual hydration in fresh rat tissue samples can vastly alter their extracted terahertz (THz) optical properties and influence their health assessment. Fresh (as opposedExpand

Dual-polarized highly sensitive plasmonic sensor in the visible to near-IR spectrum.
We propose and numerically characterize the optical characteristics of a novel photonic crystal fiber (PCF) based surface plasmon resonance (SPR) sensor in the visible to near infrared (500-2000 nm)Expand

Analysis of millimetre-wave polarization diverse multiple-input multiple-output capacity
TLDR
We show that the inclusion of a third orthogonal dipole provides orientation robustness in this setting, as well as in a rich scattering environment, by means of a Rician fading channel model covering all orientations for a millimetre-wave, tri-orthogonal, half-wave transmitter and receiver employing polarization diversity.
