使用双层镍基亚波长周期结构开发了具有非常简单的法向光入射几何结构的磁场传感器。由于场的周期结构内本征模式的相位变化，所制造的镍亚波长结构的折射光谱的峰值随着外部磁场的增加而显着移动。
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.
