A Superconductor-Based Magnetohydrodynamic Shielding System for Hypersonic Re-Entry: MEESST

In this paper, we propose a shielding system for impulse ground penetrating radar applications (GPR). The structure of shielding system is designed for our real impulse GPR application at 200 MHz central frequency for improving the deep penetration. The shielding system makes high quality of signal transmission from transmitter antenna to receiver antenna for impulse GPR system. It not only makes lowest T/R antenna coupling, high performance of antennas, preventing external noise but also reduces unnecessary air radiation which damages to the health of GPR user. A commercial absorbing material with a short thickness of 40mm is used to reduce the reflection of upper side of antenna in the cavity of shielding system. The design procedure is derived and its performance is explained. Shielding system is designed, simulated and optimized successfully in CST 2013 software. And it is fabricated with a good measurement results.

The performance improved of focusing deep hyperthermia inductive heating for breast cancer treatment using magnetic fluid nanoparticles with magnetic shielding system has been presented in the paper and the results are discussed. It is a technique challenge in hyperthermia therapy is to control locally heat the tumor region up to an appropriate temperature to destroy cancerous cells, without damaging the surrounding healthy tissue by using magnetic fluid nanoparticles and cylindrical metal shielding with aperture. We show that the magnetic field intensity can be controlled by changing the aperture size to suitable. In addition, the position of the heating can be controlled very well with the magnetic fluid together with shielding system. In the simulation, the inductive applicator is a ferrite core with diameter of 7 cm and excited by 4 MHz signal. Results have shown that the temperature increments depend on the magnetic fluid nanoparticles. In addition, the magnetic field intensity without damaging the surrounding healthy tissue when used magnetic shielded system. These results demonstrate that it is possible to achieve higher temperatures and to focus magnetic field intensity where the nanoparticles and magnetic shielding system are used.
