COMPUTER SIMULATION FOR OPTIMAL CONTROL OF MICROWAVE-INDUCED HYPERTHERMIA C. De Wagter * ABSTRACT A computer profiles simulation to calculate biological and control tissue transient temperature To express in plane multilayered is presented. the temperature increase as a function of time-varying incident microwave heating and artificial surface cooling, a semi-discrete finite difference

APERIDRE SYNTI-JES I S TI-IERMOGRAPHY A.R. Gillespie, C.G.T. Haslam and N.C. Haslam ABSTRACT The radio~astronomical technique of aperture synthesis is proposed for use in medical applications to give, non-invasively, a thermal image of a large fraction of the body to a depth of several centimetres. The operating principles are discussed and some possible applications given, including canc

ON POSSIBILITIES THERMOGRAPHY OF THERMAL PATTERN RECOGNITION BY CORRELATION MICROWAVE L. BELLARBI, A. MAMOUNI, J.C. VAN DE VELDE, Y. LEROY ABSTRACT New results concern Correlation Microwave Thermography, a radiometric process, able to complement Microwave Thermography in biomedical applications. Experimental data point out a spatial resolution which, for steep thermal gradients, can reach ab

DESIGN OY VIVALDI ANTENNA FUR MICROWAVE INTEGRATED CIRCUITS APPLICATIONS Y.Abdel Aziz, H. El Hennawy, S.Nahrous*, K.Schunemann** ABSTRACT A computer-aided design of' the vivaldi antenna is developed. A gain of 12db and a side lobe of-17db are obtained from antenna of length 2 0, and operating in the x-band. The VSWR is less than 1.55 and the gain varies by only 1db over a bandwidth of nearl

MICROSTRIP ARRAY FOR REFLECTOR FEED APPLICATIONS P.S.Hall * and C.J.Prior * ABSTRACT The performance of a small microstrip array for use .as a reflector feed is reported. Patch arrays incorporating both coplanar and reduced height electro magnetically coupled feed networks have been investigated. Radiation from the feed network is found to be significant and results in some copolar pattern

THE INPUT IMPEDANCE OF A RECTANGULARMICROSTRIP RESONATOR FED BY A MICROSTRIP NETWORKON THE BACKSIDE OF THE SUBSTRATE Gregor Gronau, Hugo MoschUring and Ingo Wolff * ABSTRACT Analytical expressions for the input impedance of rectangular microstrip resonators used in the microstrip array antennas, fed by a microstrip network on the backside of the substrate are derived. Using the feedingtechnique



ANALYSIS OF A SUSPENDED PATCH ANTENNA EXCITED COUPLED INVERTED MICROSTRIP FEED BY AN ELECTROMAGNETICALLY Qiu Zhang, Yoshiro Fukuoka, Tatsuo Itoh and Luo Su* ABSTRACT A suspended patch antenna electromagnetically excited by an inverted micros trip line has been studied based on a full-wave transmission line analysis in conjunction with a microwave network theory. The input impedance calcul

A MULTIPORT PATCH ANTENNA FOR MOBILE COMMUNICATIONS R. G. Vaughan x) and J. Bach Andersen xx) ABSTRACT Application of the circular patch antenna at the mobile is discussed. Diversity branches are available from the same patch by feeding at different backplane ports. The conditions for diversity action and appropriate analysis of the antenna are reviewed. 

HOLE COUPLING BETWEEN FIN LINES AND CAVITY RESONATORS Gert Evers* and Wolfgang J.R. Hoefer** ABSTRACT This paper describes the magnetic coupling between fin lines and cavities resonating in the circular TEOl2-mode. The coupling coefficient has been measured and calculated as a function of hole size and fin gap width for unilateral and bilateral fin lines.
