Abstract :
This paper considers the influence of radiation resistance on the signal to noise (SNR) ratio in magnetic induction sensors and communication systems. It is shown that a magnetic sensor or receiver has a specific optimal frequency in which its SNR is maximal. It is also found that although magnetic induction systems are designed to operate under a magneto-quasi-static approximation, the radiation resistance may be a dominant noise factor even at low frequencies.
