Embodiment Construction
[0027] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0028] figure 1 A spherical multilayer film structure for polarization compensation is described.
[0029] The 101st layer is an air layer, and the refractive index is set to n0. The electromagnetic wave is incident from the 101st layer, and is transmitted and reflected between 101 and 102. 102 is the first medium of the ABAB structure of the spherical multilayer film, with a refractive index of n1 and a thickness of d1. 103 is the second medium with a refractive index of n2 and a thickness of d2. 104 and 105 are the same as 102 and 103 respectively , forming a periodic repeating structure. 106 is the base, the refractive index is ns, and the thickness is ds.
[0030] For spherical multilayers, the field equations can be described using modified Maxwell's equations:
[0031] The incident signal will be reflected and transmitted at each layer, and t...
