Abstract:
In order to achieve the series connection of insulated gate bipolar transistors (IGBTs), resistor-capacitor-diode (RCD) snubber circuit, which was chosen for active voltage sharing, was analyzed by mathematical methods, then the RCD snubber circuit p...

Abstract:
When a pulse forming line (PFL) is being charged, the voltage will be not the same on the PFL for the short charging time and certain length of the PFL. Therefore, the output voltage on the load resistance is also changed. This is researched in theor...

Abstract:
Terahertz (THz) pulses after spatiotemporal shaping have been widely applied to THz spectroscopy and imaging. We simulate the shaping effect of rectangular and circular apertures by employing the three-dimensional (3D) finite-difference-time-domain (...

Abstract:
A fourstage cascade terahertz mesh bandpass filter has been designed according to the atmospheric absorption windows of terahertz waves. The center frequency of the filter is 0.25 THz, the bandwidth is 0.1 THz at 3 dB, the transmittance is greater th...

Abstract:
The existing input structure for confocal waveguide is narrow-banded. Thus a quasi-optical input structure for 0.4 THz confocal waveguide gyro-TWT is designed based on Gaussian transformation, and the input mode is HE06 mode. This structure is compos...
