研究了两非线性单轴反铁磁晶体交界面上表面波的传播特性 .理论分析和数值模拟表明 :入射电磁波只有同时满足频率阈值和功率阈值条件才能在该非线性波导系统中形成稳定传播的表面波 .随着传输功率的不断提高 ,磁场峰值将由一非线性晶体中跃入另一非线性晶体中 ,并逐渐靠近交界面 .表面波动率变化不会对交界面处的磁场振幅产生影响 ,频率是影响其振幅大小的唯一因素 .
The propagation characteristics of the surface wave at the interface between two nonlinear uniaxial antiferromagnetic crystals are studied.The theoretical analysis and numerical simulation show that the incident electromagnetic wave can form stable propagation in the nonlinear waveguide system only when both the frequency threshold and the power threshold condition are satisfied With the continuous increase of transmission power, the peak value of magnetic field will jump from one nonlinear crystal to another non-linear crystal and gradually close to the interface.The change of surface volatility will not affect the magnetic field amplitude at the interface, Frequency is the only factor that affects its amplitude.
