An account is given of the development and design of a superheterodyne receiver for wave-lengths of 17 cm., the receiver incorporating a stabilised intermediate frequency amplifier.
Electrically-tunable membranes with controllable permeability have been proposed and experimentally demonstrated by combining nano- and micro-structured superhydrophobic surfaces with the phenomeno
In this paper, we investigate secure communications by introducing superimposed pilots for multiple antenna system.
A two-level metal process for a fourth generation 1.0micron CMOS technology has been developed which yields superior step coverages and void-free dielectrics without introducing complicated process
We have observed a periodic superlattice modulation in Nd sub 2 CuO sub 4 and in the electron doped Nd sub (2-x) Ce sub x CuO sub 4 and Nd sub 2 CuO sub (4-x) F sub x systems by electron diffractio
Summary form only given.
We present the realization of a quantum cascade (QC) laser employing so-called "chirped" superlattices and operating at 17 μm, which represents the first demonstration of a semiconductor injection
We demonstrate a novel 10.8 um superlattice infrared detector based on doped quantum wells of GaAs/A1GaAs.
We demonstrate a novel 10.8microns superlattice infrared detector based on doped quantum wells of GaAs/AlGaAs.
We observe the spontaneous re-emergence of long-range order in the electrochemical deposition of the metal dendrites very far from equilibrium.
