Abstract
There are two types of resonating magnetically coupled coils, namely, open-circuit or short-circuit type coils. While both could be operated as a magnetic resonance coupling, the open-circuit type can self-resonate without a resonant capacitor. On the other hand, the short-circuit type requires an external capacitor. Also, there is a difference in the resonant frequency. Open- and short-circuit type coils will be discussed in this chapter.
