New shape induction loop for small and medium-size rooms

This paper proposes a loop which provides an effective field cancellation in all four directions — a full rectangular cancellation loop. This loop consists of three concentric rectangular contours and they form a closed circuit. According to our best knowledge, such system has not been studied before. The proposed loop has two parameters, which allow to carry out a more efficient optimization procedure. This loop is suitable for rooms with a size up to 300 m2. The benefits of the proposed loop are: reduced wire consumption, symmetry of field distribution and the use of only one amplifier.
