Since Finite-Difference Time-Domain (FDTD) method was proposed by Yee in 1966, its hardware acceleration problem arouses much concern. In this paper, how to use GPU+COW parallel computing system to accelerate the FDTD method was introduced briefly. The acceleration scheme and the simulation results were presented, and then the feasibility and efficiency of(More)
Microwave dielectric oscillation frequency source uses a small size, light weight, high Q value, inexpensive dielectric resonator (DR) as a resonant unit. It has the advantages of miniaturization, low phase noise, high stability and low cost and had already been widely applied, so the research on microwave dielectric oscillator has also become one of the(More)
Low temperature plasma technology as a special processing method has been used very widely in semiconductor technology, but when process the wafer which diameter is larger than 300mm, the uniformity of semiconductor wafer will become worse, and then the productivity gets lower. These bad results all attribute to one key reason that the plasma excited by the(More)
The vehicle velocity of an operational system is recognized by the bridge responses with a pattern search algorithm in this paper, which provides an approach to monitor the vehicle velocity in civil engineering. The Pattern Search algorithm is represented by a preliminary numerical example. The operational bridge system is simplified to a moving mass and a(More)
