It uses an electromagnetic impulse plus anticancer drugs to treat a tumor. The technique is very easy to control and operate and is of little harm to normal tissue. Especially, it is very efficient in curing flat tumors. We have used ECT to treat S-180 sarcomas in KunMing mice. In the experiment, we explored the optimal parameters of the electromagnetic impulse used in the treatment and acquired elementary results.","PeriodicalId":129734,"journal":{"name":"Asia-Pacific Conference on Environmental Electromagnetics, 2003.

Other than many conventional synthesis methods, the genetic algorithm (GA) can be used to synthesize such arrays to reach the requirement of the sidelobe level. The optimized variables in the nonuniformly spaced array are usually chosen as the element positions. In the application of digital beamforming antenna systems, the optimized variables may be chosen as element positions, amplitudes, phases or some combination of them, which provide more degrees of freedom to the synthesis of arrays than before. Simulation results show that this method is valuable.","PeriodicalId":129734,"journal":{"name":"Asia-Pacific Conference on Environmental Electromagnetics, 2003. CEEM 2003.

This method can successfully predict the performance of the finite array as well as greatly reduce the computer time and memory usage especially in the optimization of the finite array.","PeriodicalId":129734,"journal":{"name":"Asia-Pacific Conference on Environmental Electromagnetics, 2003.

Nonuniform meshes and reduced c FDTD method were adopted to solve the contradiction of selecting space step and time step: this makes it possible to calculate the steel shielding efficiency of large dimension. The interaction of shielding enclosure and loop antenna was modeled. The setup of the simulation coincides with the real conditions of engineering testing. The conclusions from the numerical calculation are: the waveform of EMP transparent though the steel shielding enclosure is greatly different from the incident EMP waveform. The rise time changes to be very slow and the width of pulse gets long. The calculating and real testing indicate that the shielding efficiency of the steel enclosure to the EMP with longer rise time (/spl mu/s) and wider duration (1ms) is only about 40 dB, the rise time of transparent pulsed magnetic field reaches ms and the pulse width is more than 10ms. The shielding efficiency of the steel enclosure to low frequency electromagnetic field is much lower.","PeriodicalId":129734,"journal":{"name":"Asia-Pacific Conference on Environmental Electromagnetics, 2003.
