The calculations of the optical conductivity, relative to the transitions due to surface states, are performed with the light polarized perpendicularly to the surface of the film. In the spectral range where this sort of absorption exists, the superficial film shows a selective anisotropy. We develop the importance of this an-isotropy on the validity of the methods concerning the measurements of the optical parameters and specially the conductivity. Our calculations are compared with the experimental optical parameters for potassium. A good agreement is obtained between our results and the experimental values in the infrared spectral range.
相对于由表面态引起的跃迁，光导率的计算是在光垂直于薄膜表面偏振的情况下进行的。在存在这种吸收的光谱范围内，表面薄膜呈现出选择性各向异性。我们阐述了这种各向异性对于光学参数测量方法特别是电导率测量方法有效性的重要性。我们的计算结果与钾的实验光学参数进行了比较。在红外光谱范围内，我们的结果与实验值取得了良好的一致性。
