Far-infrared absorption is used to probe the optical conductivity of metallic GaAs:Si sheets imbedded in GaAs by molecular beam epitaxy.

Arno Penzias and Robert Wilson, working at AT&T Bell Laboratories, discovered the 3K black-body radiation that is the remnant of the origin of our universe.

We present far-induced reflectivity spectra of seven samples of ceramic superconductors in the Ba-Y-Cu-O system with transition temperatures near 93K.

Quantum-cascade lasers operating above 20 mum (at lambda similar to 21.5 mum and lambda similar to 24 mum) wavelength are reported.

Summary form only given. We report the first QC laser operating above 20 μm, in particular at a maximum wavelength of 21.5 μm.

The large Faraday rotations of Mn-containing diluted magnetic semiconductors has led to their consideration for use in magnetooptical isolators.

In all wireless systems, the first operation that must take place at the receiver is the acquisition of the carrier and timing.

Efficient subband structures that aim at fast adaptation of fractionally spaced equaliser, 0;SF), by exploiting the `prewhitening' effect that a subband decomposition h;is on the spectral dynamics

We propose an adaptive control scheme, based on the least mean squares algorithm, for electronic equalization of polarization mode dispersion.

We propose a fast-adapted subspace tracking algorithm for background subtraction in video surveillance.
