Abstract:
A resonator circuit comprising:a first resonator having a resonance frequency, said first resonator further comprising: a circuit combination comprising a first capacitance connected in series with a single inductance, said single inductance comprising an air coil; a second capacitance connected in parallel with said circuit combination; a second resonator having resonance frequency substantially equal to the resonance frequency of said first resonator, said second resonator comprising: a circuit combination comprising a first capacitance connected in series with a single inductance, said single inductance comprising an air coil; and a second capacitance connected in parallel with said second combination; wherein said second capacitance of said first and second resonators each has a value that is substantially greater than the value of said first capacitance of said first and second resonators respectively; and wherein said first and said second resonators are magnetically coupled to one another.
