This Wei solving equations obtains.Following form should be had by meeting surface wave (TE wave) electric and magnetic fields existing for interface:
Wherein i=1 represents magneto-optic memory technique region, and i=2 represents areas of dielectric.Substitute into maxwell equation group:
Further according to constitutive relationship and boundary condition, the wave vector k about surface magnetic wave can be obtainedzTranscendental equation:
Wherein,For the Effective permeability of magneto-optic memory technique.This transcendental equation can be asked by numerical solution
Solution, finally obtains kzValue.It can also find out from equation, since equation includes μκkzItem, so, surface magnetic wave have it is nonreciprocal
Property (one way propagation).

The magnetic field at place be vertical paper inwards.When light wave is inputted from light input end 1, while in magneto-optic material layer 3,4 and dielectric layer 5
Interface generates the surface magnetic wave of unidirectional positive transmission, finally exports from light output end 2；When light wave is inputted from light output end 2, by
In the nonreciprocity of surface magnetic wave cause light wave can not inside device reverse transfer, to can not be exported from light input end 1, light
Energy is all blocked at light output end 2.It can be seen that, light wave can be limited in well in turn waveguide simultaneously, damage
Consumption value is very low.
