Development of systems for long-distance communications using laser beams is of considerable current interest. A major problem is to avoid losses in transmission systems for light.
Low-noise microwave CW oscillations have been obtained from metal-semiconductor-metal (MSM) structures made from a 10-/xm thin slice of silicon sandwiched between two PtSi Schottky barrier contacts
This paper describes a microprocessor-based (MAC-8/MAC-Tutor) automatic frequency controller (AFC) that has applications to satellite communications systems.

Data communication systems in current use generally require substantially more bandwidth than the Nyquist minimum of one-half cycle per symbol.
Cylindrical magnetic domains (bubbles) are, by now, well known. Their device applications1 and theoretical description2 have been adequately described. We shall call these bubbles "normal" (NB).
