In a planar multilayer dielectric structure with graphene inserted as a boundary surface current, the optical transport properties for the transverse electric/magnetic mode have been investigated using the matrix transfer method. When an arbitrarily polarized wave transmits through the dielectric layers, the phase difference of the transmitted light between two vertical polarization directions at the terahertz frequency region is variable. The similar dependence of phase difference at zero points on the graphene Fermi energy and the number of graphene layers offers an efficient and reliable experiment method for identifying graphene flakes. The graphene broadening width can be applied to tune the value of the phase difference, but not the positions with zero phase difference. The ellipticity can be determined by the phase difference and the incident linearly polarized direction. This phenomenon is similar to the presence of the cyclotron resonance case in a traditional two dimensional electron gas.

在插入石墨烯作为界面电流的平面多层电介质结构中，已经使用矩阵转移方法研究了横向电/磁模式的光学传输特性. 当任意偏振波通过介电层时，太赫兹频率范围内两个垂直偏振方向的透射光的相位差是可变的。零点相位差对石墨烯费米能量和石墨烯层数的相似依赖性为识别石墨烯薄片提供了一种有效且可靠的实验方法。石墨烯加宽宽度可用于调整相位差的值，但不适用于零相位差的位置。椭圆率可以由相位差和入射线偏振方向确定。这种现象类似于传统二维电子气中存在回旋共振的情况。
