The determination of transmission-line characteristic impedance and propagation constants from two-port S-parameter measurements is disturbed by half-wavelength resonances. We demonstrate this effect for on-wafer measurements of coplanar lines. Two n

A noise model based on an equivalent circuit is applied to an HEMT. Besides the frequency dependence of the most important noise parameters (Fmin, Xopt, Xopt, RN) two apparent experimental facts are explained: the limited Ropt, Xopt and the increase

Experiments on the propagation of TG-modes in a weakly inhomogeneous plasma are reported. The modes travel from the high density part (ω ωpe). The wavelength decreases as expected but an increase of the longitudinal fieldstrength predicted by colli

Les mesures du courant de plasma et de la tension montrent une phase avalanche avec croissance du courant exponentielle dans les premieres 200 μs et une phase de striction entre 200 et 400 μs. Le taux de croissance depend des champs magnetiques per

Two wide spreaded methods for the measurement of plasma fluctuations are investigated both theoretically and experimentally. In limited regions of frequency and wave number, the fluctuation amplitudes obtained by probes and optical line radiation sho

The equilibrium of a magnetized Helium plasma is disturbed by a pulsed Trivelpiece-Gouldwave. The electrons obtain the energy by linear collisionless wave absorption. The relaxation phenomena of density and energy are explained in terms of two relaxa

The parametric decay process in inhomogeneous layers existing near the plasma boundaries or in front of antennas and probes in a plasma has been investigated. The linear enhancement of the pump field near ω = ωp, the threshold fieldstrength, the wa

Standing cyclotron harmonic waves below the second harmonic are observed using the noise radiation of a mercury discharge tube at 1465 MHz. From the positions of the Buchsbaum-Hasegawa resonances the density profile and the electron temperature are d
