The transmission theorem of cascade AWGs for dispersion compensation system based on time-space conversion is analyzed,and compared with the system of lightwave signal process of cascade grating-double lenses.

Electrostatic discharge current analyzed by transmission line theory;

The arithmetic of Hooke-Jeeves is used to compile the optimization program using the transmission line theory.

Aiming at electromagnetic interference of cable in interconnected system,this paper simulated and computed the crosstalk of coaxial cable,based on the transmission line theory.

For the electric or magnetic currents on the patchs or apertures of the multi-layered FSS,the coupled matrix among them can be gained through the generalized transmission-line theory when the self impedance or conductance matrix are gotten in the method of lines,and the equations for the whole structures is established.

Aimed at the feature that the locality of axis of the armature mmf is determined by the brush in dc motor, a new concept on clamp is proposed.

This converter uses a simple auxiliary circuit without the active switch and lossy components so that the voltage stress of secondary rectifier diode is reduced and the current to charge or discharge clamping capacitance is self-adjusted in accordance with the load.

In development of the power stage for a 2 kVA high frequency on line UPS,methods of anti parallel diode across the serial resistor and active clamps are adopted to reduce the gate voltage spikes over MOS gated inverter power switches during their turn off.
