A MICROWAVE-LASER INSTRUMENT FOR MEDICAL TREATMENT
Z. Ding, H. Jiadong
A MICROWAVE-LASER INSTRUMENT FOR MEDICAL TREATMENT Zang ding* Huang Jiadong** ABSTRACT A multiple-function instrument for medical treatment is in this paper. A special type microstrip antenna is adopted. ations of micromave and laser beams are merged into a single to stimulate the acupuncture points of human body. These two radiations work in coordination with each other, so that the effect

V.I. Ponomaryov , A.I. Gorb, O.A. Ksenofontov
TROPOSPHERIC REMOTE SENSING BY RADIODATA * V. I. PONOMARYOV, I. GORB, O. A. KSENOFONTOV A. ABSTRACT The method of tropospheric refractive index height profile remote sensing by radiosignal integral Doppler frequency measurements and method of tropospheric statistical parameter height profile remote sensing by refractometry phase measurements were explored by conducted experiments. Numerical analy

MODAL ANALYSIS OF DISCONTINUITIES IN PLANAR TRANSMISSION LINES: USING ORTHOGONALITY AS THE CRITERION FOR SELECTING MODES
A. Casanueva, Ma. M. Borge, J.L. García, A. Mediavilla
MODAL ANALYSIS OF DISCONTINUITIES IN PLANAR TRANSMISSION LINES: USING ORTHOGONALITY AS THE CRITERION FOR SELECTING MODES A. Casanueva, Ma. M. Borge, J.L. Garcia, A. Mediavilla ABSTRACT The technique of modal analysis has been used together with the spectral domain approach (SDA) to analyze single and cascaded step discontinuities in planar transmission lines, particularly in boxed microstrip and
THEORY AND APPLICATIONS OF MULTIPORT STRUCTURES USING MAGNETOSTATIC WAVES
S.V. Zagriadski
THEORY AND APPLICATIONS MAGNETOSTATIC WAVES S V Zagriadski ABSTRACT OF MULTIPORT STRUCTURES USING This paper reports an electrodynamic analysis and possible applications of tunable multiport ferrite-dielectric structures with parallel transmission lines of an arbitrary type coupled through magnetostatic modes of magnetized multilayered thin ferrite films. The structures are supposed to be excite
ANALYSIS OF FIELDS IN MICROWAVE OPEN RESONATORS WITH DETAIL ON PERFECT AND IMPERFECT MIRRORS
P.N. Fletcher, L.J. Auchterlonie
ANAL YSIS OF FIELDS IN MICROWAVE OPEN RESONATORS WITH DETAIL ON PERFECT AND IMPERFECT MIRRORS P.N. Fletcher, L.J. Auchterlonie ABSTRACf Recently completed computations of the field profiles existing within various microwave open resonator configurations are described for the following situations - perfectly aligned planar and spherical mirrors; misaligned spherical mirrors; imperfectly shaped sph
ANALYSIS OF E-PLANE WAVEGUIDE JUNCTION CONTAINING PARTIAL HEIGHT AND FULL HEIGHT METALLIC POST
Y.Y.Tsai, A.S. Omar
ANALYSIS OF E-PLANE WAVEGUIDE JUNCTION AND FULL HEIGHT METALLIC POST CONTAINING PARTIAL HEIGHT Y.Y. Tsai1 and A.S. Omar2 ABSTRACT A method is presented to analyze a three-port E-plane waveguide junction containing partial height and full height metallic post. The method is based on the equivalence principle and cavity field expansions. The validity of the method is confirmed by plotting the fi
RADIATIVE MODES OF OPEN MICROSTRIP WITH APPLICATIONS
T. Rozzi, G. Cerri
RADIATIVE MODES OF OPEN MICROSTRIP WITH APPLICATIONS Tullio Rozzi*, Graziano Cerri* ABSTRACT The bound modes of open microstrip are well known. These however do not constitute a complete spectrum. Continuous radiation and localized (reactive) modes are excited at discontinuities in microstrip circuits and antennas. This part of the spectrum has not been investigated before and, consequently, up t

I.B. Vendik, D.I. Kaparkov, S.F. Karmanenko, V.M. Pchelkin, A.V. Shchepak
HIGH- TEMPERATURE SUPERCONDUCTOR PHASE-SHIFTER I B Vendik. D I Kaparkov. A V Shchepak * ABSTRACT S F Karmanenko. V M Pchelkin. Design problems of high-temperature superconductors (HTSC) film digital phase shifters are discussed. Current controlled HTSC film switch is used as a switching element. This allows an uniform fabrication of all components of the HTSC microwave integrated circuits. T
ANALYSIS OF MICROSTRIP DISCONTINUITIES IN MULTILAYERED SEMI-CONDUCTOR SUBSTRATES
J. Martel, R.R. Boix, M. Horno
ANALYSIS OF MICROSTRIP CONDUCTOR SUBSTRATES DISCONTINUITIES IN MULTILAYERED SEMI- J. Martel, R.R. Boix, M. Homo 1 ABSTRACT The equivalent circuits and the scattering parameters of microstrip open-end, gap and crossover discontinuities are calculated in the case in which the conducting strips are embedded in a stratified substrate consisting of layers of insulator and/or semiconductor materia
