STATUS OF MILLIMETER WAVE TECHNOLOGY AND APPLICATIONS IN THE U.S.
STATUS OF MILLIMETER WAVE TECHNOLOGY AND APPLICATIONS IN THE U.S. James c. wiltse. ABSTRACT . Recent progress in the millimeter-wave summarized. In the technology area there field will be are significant developments in HEMT solid-state oscillators and in passive component development. In the past several years there have been major investigations of atmospheric effects (scintillation and
MICROWAVE APPLICATIONS IN MEDICINE IN THE U.S.A. - A SHORT OVERVIEW
MICROWAVE APPLICATIONS IN MEDICINE IN THE U.S.A. - A SHORT OVERVIEW' Arye Rosen* ABSTRACT In the last ten years microwaves have been used increasingly in the U.S.A. in the areas of diagnostic and therapeutic medicine as well as in surgery. For example passive radiometry is an important for measuring tool the temperature of subcutaneous regions of the human body non-invasively with the potential
MULTI-FUNCTION GaAs MMICs FOR SYSTEM INSERTION: ISSUES AND TRENDS
MULTI-FUNCTION GaAs MMICs FOR SYSTEM INSERTION: ISSUES AND TRENDS (Invited Paper) Fazal AII* ABSTRACT: This paper describes the design approaches development and issues related to the Examples of of multi-function GaAs MMICs for system insertion. highly integrated GaAs MMICs developed for specific system applications are also presented.
INDUSTRIAL APPLICATIONS OF MICROWAVE IMAGING
INDUSTRIAL APPLICATIONS OF MICROWAVE IMAGING J. B. Detlefsen * ABSTRACT After a definition of the term "Imaging" in the microwave field, optical and microwave images will be compared in terms of information content, method and simplicity of access. The current and potential future industrial applications including the fields of robotics and microwave vision, biomedical applications, imaging o
TRENDS IN MEASUREMENTS IN THE mm-WAVE RANGE
TRENDS IN MEASUREMENTS IN THE mm-WAVE RANGE. H. P. Groll * ABSTRACT The tendency to expand the frequency range of measurement equipment one can observe for coaxial systems, which measure in a continuous sweep the whole range up to 50 or 60 GHz. This is typical for automatic vector network analyzers. Also the new spectrum analyzers enlarge the unambiguous frequency range using new YIG preselecti
ASSESSMENT OF POTENTIAL APPLICATIONS FOR NEW MICROWAVE DEVICES AND INTEGRATED CIRCUITS AT HIGHER FREQUENCIES
ASSESSMENT OF POTENTIAL DEVICES AND INTEGRATED D Pons., P Briere.. ABSTRACT APPLICATIONS FOR NEW MICROWAVE CIRCUITS AT HIGHER FREQUENCIES and J Magarshack.. The communication needs in the next future will call on millimeter-wave (mm-wave) techniques for the transmission of information. We describe briefly two examples of mmwave systems which are worked on in the "AIMS" Esprit project. These fut
MICROWAVE SIGNAL LIMITERS AND COMMUTATORS BASED ON SUPERCONDUCTING FILMS
MICROWAVE SIGNAL LIMITERS SUPERCONDUCTING FILMS v AND COMMUTATORS BASED ON 0 G Vendik. A Yu Popov ABSTRACT . M M Gaidukov. S G Kolesov. A B Kozyrev. An essential property of the superconducting film is S-N transition which can be induced by ac or dc current and exhibits in the large change of the film surface resistance. The S-N transition is used for performing microwave signal limiters
SILICON MONOLITHIC MILLIMETERWAVE INTEGRATED CIRCUITS
SILICON MONOLITHIC INTEGRATED P. Russer Abstract MILLIMETER WAVE CIRCUITS 1 Silicon monolithic millimeterwave integrated circuits (SIMMWICs) for frequencies up to above 100 GHz are discussed. In silicon circuits IMPATT diodes may be used as the active devices whereas mixer and detector circuits may be realized with Schottky diodes. IMPATT diodes as well as Schottky diodes may be integrated in pl

NEW SOLID STATE DEVICES AND CIRCUITS FOR MILLIMETER WAVE APPLICATIONS E. Kollberg. ABSTRACT In this paper we will address some new devices and circuits conceptually different to well known microwave devices and circuits. Hence we will briefly discuss devices such as ,the quantum well diode for oscillators, multipliers and mixers, the back to back Barrier n-n+ (bbBNN) varactor diode for multipliers
MICROWAVE TECHNOLOGY IN THE TERAHERTZ REGION
MICROWAVE TECHNOLOGY IN THE TERAHERTZ REGION Hans H. Brand* ABSTRACT . Electromagnetic waves with frequencies between 0.1 THz and some 10 THz cover the gap from the millimeter wave bands to the infrared optical region. Coherent microwave technology concerning signal generation and detection has been introduced in this THz-region to a steadily growing extent in the past, mainly forced by applica
