Abstract: Some computing techniques of the unimoment method for solving electromagnetic scattering problems of a dielectric cylinder with arbitrary cross section are investigated. Rieatti transformation is used in solving the set of linear equations for findin...
Abstract: Higher order modes coupling characteristics in H11O, circular bending waveguide are analyzed according to the coupled wave equations, and coupling coeffecients of E01O, H21O, modes and their amplitudes are computed. A broad-band H21O, E01O mode filte...
Abstract: The current modulation characteristic of PIN modulator is analyzed, and its highly-nonlinear characteristic appearing on a linear coordinate is discussed. A circuit com-pensation method, in which a logarithmic network is mainly used, is presented for...
Abstract: Starting from the current-voltage equation given by A. Van der Ziel (1976), a dif-ferential equation of the normalized fluctuation is developed. Expanding the Pourier transform of the fluctuation into a power series in the parameter j and solving the...
Abstract: A description of a phase-locked loop (PLL) is given, which is successfully used in an X-band linear PM inicrowave source with 6 s pules width, 30 MHz bandwidth and 1 ms FM pulse cycle. A phase-locked method is used to obtain the linear FM pulse signa...
Abstract: A computer program for calculating emission current in an electron gun has been worked out, and good agreement between calculations and experiments has been achieved. The computation model is based on the statistical theory of thermal electron emissi...
Abstract: A basic principle of spiral strip line generator (SSLG) for obtaining millimicrose-cond pulsed high voltage is described. Design method of SSLG with a short switch is given. The SSLG s inner end is the high -voltage output end, and its outer end is g...
Abstract: An investigation of the working state of the ignition type thermionie energy con-verter (TEC) is carried out and a physical model is established for analysis and calcu-lation. The region between the positive and the negative electrodes is divided int...
Abstract: The formula and program for calculating the total and negative first harmonie interaction impedance from the data of large perturbation measurement are given. This program is a part of the programs for CCTWT design.
