    It is well-known that some workers in scientific research laboratories are enormously more creative than others. If the number of scientific publications is used as a measure of productivity, it is found that some individuals create new science at a rate at least fifty times greater than others. Thus differences in rates of scientific production are much bigger than differences in the rates of per... View full abstract»

    This paper is a general introduction to the field of amplification and generation of microwaves using molecular rather than electronic processes. The basic physical properties of molecular systems as related to amplification are reviewed. The properties of molecular amplifiers, such as gain, bandwidth, saturation power, and noise figure are discussed, and several specific types of amplifiers are d... View full abstract»

    New devices are considered in which electrons or holes are injected directly into space-charge regions of reversebiased junctions avoiding the diffusion of carriers through field-free regions. The case considered is one in which the junction is biased at a voltage such that the injected carriers are multiplied by the avalanche process. A device of this type shall be called a spacistor. It is shown... View full abstract»

  • Ferrite Apertured Plate for Random Access Memory

    Plates with an array of apertures molded from rectangular loop ferrite can be used for random access memory. With the relatively close center-to-center spacing equal to twice the hole diameter there is negligible interaction between adjacent holes. The nonconductive ferrite plate can be coated with a conductive pattern to form a "printed" winding linking all holes in series. The plates can be stac... View full abstract»

    The transistor is a nonunilateral device which, if appropriately terminated, can become unstable at frequencies where its "internal feedback" is sufficiently large. At such frequencies, the maximum power gain is infinite and the transistor may oscillate. This paper discusses the maximum power gain realizable as a function of a required degree of stability. A "stability factor" is defined in terms ... View full abstract»

  • Ferrod Radiator System

    Commercially available ferrites with low dielectric and magnetic losses at microwave frequencies have brought about the development of ferrod radiator systems for 3-cm wavelength. These ferrites are, in general, characterized by high dielectric constants (approximately 13) and initial permeabilities slightly less than unity. The use of these ferrimagnetic materials as ferrite rod (ferrod) radiator... View full abstract»
