Resonance Frequency of Two Electrically or Magnetically Coupled Resonant Circuits
Based on two independent methods of eigenvalue theoretical analysis and circuit simulation,the relationship between the new resonance frequencies of two resonant circuits with electric coupling or magnetic coupling and the value of the coupling capacitance or coupling inductance are quantitatively calculated.The resonance frequencies of the two coupling circuits show dif-ferent characteristics.The analysis of this coupled resonant circuit opens up a new way to tune the resonant frequency by using the coupling type and coupling strength in the actual circuit design process,and expands the content of the uncoupled resonant circuit in the existing teaching.
