ADVANCES PROGRESS IN THE FIELD OF MICROWAVE WAVE RADIOMETRY GENERATED BY THE TECHNOLOGICAL IN THE MILLIMETER + REGION K. Gruner) Abstract Passive objects visible mapping of the environment by detection of natural radiation of is possible in the microwave region in the same way as for the and infrared part of the electromagnetic spectrum. Because of the minor weather sensitivity and the s

MilliMETER WAVE THERMOGRAPH AS SUBCUTANEOUS INDICATOR OF JOINT INFLAMMATION J. Edrich* and C.J. Smyth+ ABSTRACT Noninvasive scanning imaging technique of inflammations is described; it of human uses the joints mm wave 1 using a new remote radiation emitted by the human body. This method overcomes the depth imitations of convention- al infrared thermographs and can measure

TERATOGENIC POWER OF SHF FIELDS. TENEBRIO MOLITOR COLEOPTERON. Guglielmo d'Ambrosio(+}, Vincenzo FURTHER EXPERIMENTS ON La Manna(+}. ABSTRACT Teratogenic effects of microwaves were experimentally investigated. Larvae and six days old pupae revealed to be less sensitive than one day old ones. Energy dosage (reciprocity) law appeared to fail at short time exposures. Experiments, carried out at

A MODIFIED RADIOMETER FOR TEMPERATURE AND MICROWAVE PROPERTIES SUBSTANCES MEASUREMENTS OF BIOLOGICAL A. MAMOUNI ., F. BlIOT ., Y. lEROY. .. and Y. MOSCHETTO ABSTRACT The use of radiometers for biomedical applications needs a coherent understanding of thermal signals emitted by the tissues. In this paper, we show first, that some precautions have to be taken when measuring a temperature by

DESIGN AND APPLICATION OF SPECIAL MICROWAVE INTERFEROMETERS FOR NON-INVASIVE STUDIES OF BIOLOGICAL EFFECTS. Donald W. Griffin ABSTRACT Special microwave interferometers have been designed to make non-contact measurements of the movements associated with various physiological functions such as respiration, pulse, muscle action, reflexes, involuntary tremors, etc. For each interferometer the fac

A MICROWAVE RADIOMETRIC OF LIVING TISSUE METHOD FOR THE STUDY OF THE SEMICONDUCTOR PROPERTIES J. Bigu-del-Blanco *, A. Schneiter ** and J. C. Beal ** ABSTRACT A MW radiometric method for the study of the semiconductor properties of tissue is proposed. This method makes use of the non-linear properties of tissue in conjunction with its radiative properties as described by blackbody theory.

APPLICATION OF THE ISOPARAMETRIC FINITE-ELEMENT INTEGRAL EQUATIONS METHOD TO G. Jeng, M.H. Lean, and A. Wexler ABSTRACT A refined numerical technique, based on a variational approach using isoparametric finite-elements is presented for the solution of three-dimensional electromagnetic scattering problems. This technique allows a higher-order approximation of the unknown function over a bound

NUMERICAL SOLUTION OF THE APERTURE BACKED BY A RECTANGULAR CAVITY FIELD INTEGRAL EQUATION FOR A WIDE SLOT Kari Suneli ABSTRACT A two-dimensional vector integral equation for the tangential electric field distribution in a cavity-backed aperture is presented. The solution of the integral equation for a rectangular cavity by the method of moments is discussed. The expansion and testing funct

Walter for the cylindrical and spherical expressions wave ex- pansion coefficients of the field of an arbitrary antenna are determined, using the dyadic Green's function, expanded in the appropriate vector waves. The upper limit on the amplitudes of these
