An efficient and straightforward antenna design method is presented that maximizes the ratio of total efficiency specific absorption rate (SAR). This goal achieved with a multiport cluster technique where several ports are excited collectively appropriate feeding weights. These weights found as an eigenvalue solution formulated in terms radiated near-field power antenna. The relies on both (SAR...

conclusions we found the magnetic field assistant device to be an accurate, radiation-independent jig for close passing of guide wire after close reduction of femoral fracture. it can reduce the need for radiation during placement of guide wire for closed intramedullary nailing of the long bones. more studies are required to improve and evaluate the technique and equipment. results outcomes of ...
