摘要

磁耦合读取器/应答器附近金属的有害影响通常通过铁氧体屏蔽来减轻。谐振电路的成本是铁氧体材料的一小部分，可以通过从金属中获取能量来减少这种影响。结合电路和现场仿真及实验，提出了一种简化的理论。

Mitigation of proximity to metal for magnetically coupled transponders by use of resonant loops

Deleterious effect of metal in proximity of magnetically coupled readers/transponders is often mitigated by ferrite shields. A resonant circuit at a fraction of the cost of ferrite materials can reduce the effect by robbing energy from the metal. A simplified theory in conjunction with circuit and field simulation and experiments are presented.
