从静磁表面波MSSW各向异性理论模拟出发,提出了通过调节磁场方向来实现对MSSW滤波器带宽调制的方法,并由实验得到验证:即在微带换能器宽度一定时,可以增加(或减小)磁场与波矢k之间的角度来减小(或增大)滤波器带宽,从而简化和精确静磁表面波滤波器的设计.
From the simulation of magneto-static surface wave anisotropy,this paper presents a method to modulate the bandwidth of magneto-static surface wave filters by changing the magnetic field direction.It has been proved by experiments that when the transducer width is fixed,the filter bandwidth become widen(or narrow down) by descending(or increasing)the angle of magnetic field and wave vector k.Consequently the magneto-static surface wave filter design becomes simpler and more accurate.
