INDUCTIVE SENSING SYSTEM FOR SENSING ELECTROMAGNETIC SIGNALS FROM A BODY

The invention provides a magnetic inductive sensing system for sensing electromagnetic signals emitted from a body in response to electromagnetic excitation signals applied to the body. The electromagnetic signals are generated and sensed by the same loop resonator which comprises a single-turn loop antenna and a tuning capacitor. The loop antenna of the resonator and a signal generation means forexciting the resonator to generate excitation signals are together configured so as to optimize the value of a ratio between the radial frequency of the generated electromagnetic excitation signals and a reference frequency of the antenna, where the reference frequency is the frequency for which one wavelength of the generated excitation signals (waves) matches the circumferential length of the antenna. The ratio, which corresponds to a normalized radial frequency of the generated excitation signals, is maintained between a value of 0.025 and 0.50. 本发明提供了一种用于感测响应于施加到身体中的电磁激励信号而从所述身体中发出的电磁信号的磁感应感测系统。所述电磁信号由相同的环形谐振器来生成
