摘要

采用双层镍基亚波长周期结构，研制了具有非常简单的法向光入射几何形状的磁场传感器。制备的镍亚波长结构的折射光谱峰随着外加磁场的增加而发生明显的位移，这是由于磁场周期结构内本征模的相位变化。

Magnetic field sensing by bi-layer Ni-based subwavelength periodic structure operating visible wavelength region

Magnetic field sensor with very simple normal light incident geometry was developed using bi-layer nickel-based subwavelength periodic structure. Peaks in refraction spectra from the fabricated nickel-subwavelength structure shifted considerably with increasing external magnetic field, owing to phase variation of eigenmode within the periodic structure for the field.
