Abstract

With electromagnetic field theory

formation of the impedance of a YIG single crystal sphere resonator coupled by a loop is analyzed in this paper

When the diameter of a single crystal sphere can be compared with the diameter of a loop

a general formula of resonator impedance is derived.Considering that the surface of the magnetic pole is an ideal magnetic wall

by means of mirror method

the effect of outer magnetic pole on resonator impedance is analyzed quantitatively. The resonator impadance formula derived by author differs from those of references [1]

[2]

[3] slightly and proves that the impedance formulae given in references [4]

[5] are only suitable for the case that the radius of the single crystal sphere is much less than that of a loop.
