چکیده
We investigated the influence of using a conical end on the longitudinal electrical nearfield generated by a coaxial cable. Simulations with Finite Integration Technique show that this influence greatly varies along the longitudinal axis. Experimental measurements were also carried out. To that purpose, we designed a new set-up to measure the electrical field in one direction with a spatial resolution of 100 microns in this direction, with nearly no perturbation by the other components of the field. This set-up uses a piezoelectric sintered PZT film and a heterodyne laser probe.

متن کاملHigh Power W-Band Heavily Loaded TEOl Gyro-TWT
A broadband 140 kW, 94 GHz amplifier has been built at UCD that operates in the low loss TEol mode (Ref. 1). Because a large axial velocity is beneficial for stability and wide bandwidth, it employs a 100 kV, 5 A beam with a modest velocity ratio of vl/vz=l. To reduce the interception of electrons by the wall, the guiding center of the beam is 1&=0.45, which is slightly inside of the TEol mode ...
متن کاملDesign of a Novel Wideband Loop Antenna with Parasitic Resonators
A novel coax-fed wideband loop antenna loaded with rectangular patches and U-shaped elements is presented and studied. By inserting a pair of rectangular patches inside the strip loops and employing a pair of U-shaped elements as the parasitic resonators, two additional resonances are excited and a good performance of bandwidth enhancement can be obtained. The measured results indicate that the...
