20世纪的人们认为磁感应强度是由两个线圈之间的耦合系数k引起的。密集的通量应该只能到达非常接近的地方。 Kurs 等人彻底改变了这种常识性解释。等人。 2007 年。他们通过提高线圈的 Q 因子，展示了尽管 k 值较低（即远距离传输）的强大功率传输能力。这一成功的关键指标不是单独的 k，而是他们实验中的 k 乘以 Q [1]。
People in the 20th century believed that magnetic induction is due to the coupling coefficient kbetween two coils. Dense flux was supposed to reach only in close proximity. This common-sense interpretation was drastically altered by Kurs et. al. in 2007. They demonstrated a strong power transfer in spite of low k, i.e. at a distance, by enhancing the coil's Q factor. The key index to this success was not k alone but k times Q in their experiment [1].
