Tapered finline might constitute a radiating element compatible with planar technology and therefore be suitable for antenna arrays fed by integrated circuitry.

(Manuscript received May 16, 1967) A structure has been proposed and fabricated in which semipermanent charge storage is possible.

A Josephson Parallel Multiplier By T. A. FULTON and L. N.

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).
