【Abstract】 This paper presents a theoretical investigatoin of the effects of the induced uniaxial anisotropy on the bandwidth and group delay of magnetostatic forward volume wave(MSFVW).The expressions for the bandwidth and group delay of MSFVW are derived under magnetostatic approximation.The numerical results for Bi-doped YIG film show that the induced uniaxial anisotropy has significant effects on the bandwidth and group delay of MSFVW.Under appropriately inclined bias field,the induced uniaxial anisotropy contributes to increasing the bandwidth and improving delay linearity of MSFVW.更多还原
