In this work, we present an experimental and micromagnetic simulation study of the mode transformation dynamic spin wave well modes in magnetic stripes. With a highly precise lock-in ferromagnetic resonance measurement system, modes, including quantized backward volume magnetostatic waves can both be clearly detected transversely magnetized The transformations are field range that moments near edge stripe not fully magnetized. Further analyzation show boundary condition change potential might main reason for modes. These results helpful further understanding dynamics finite ferromagnets.
