In many branches of science and technology observations of a discrete radio source provide fundamental knowledge. In the field of radar the illuminated target serves as the discrete radio source.
For most applications to microwave communication systems, waveguides are designed in such a way that only the dominant mode can propagate.
Owing to the wide use of repeaters in modern high-grade long-distance telephone circuits and the importance of obtaining a high repeater gain without singing, the authors of the paper investigate f
Potassium titanyl phosphate is an unusually good nonlinear optical material whose use is constrained because of the difficulty of growing crystals.
The prospect of highly conductive polymer electrolytes has become an important aspect of the development of an all solid state rechargeable battery.
We review recent progress on phase retrieval receivers (Rx) employing alternative projections for coherent optical communications.
Phase-retrieval (PR) receivers can reconstruct complex valued signals using only direct detection without the use of any optical carriers.
The amplification of spontaneous emission is used to initiate laser action.
We report studies of the 1/f noise in La5/8-yPryCa3/8MnO3 (y = 0.3 - 0.4) which exhibits the metal-insulator transition (MIT) in zero magnetic field, and in Pr1-xCaxMnO3 (0.30.5), where the tran
The ternary system Cd sub (1-x) Zn sub x Te has been a leading candidate for use as a lattice matched buffer layer for a variety of Hg-containing II-VI compounds.
