摘要
运用经典振子理论,借助振子n-k蛋圆曲线及反射率半圆图,分析了高频介电常数对晶体反射光谱的影响,指出当振子强度和阻尼常数一定时,高频介电常数低的材料有利于在反射光谱中形成宽带低反射率区,可用于红外吸波。
Using classical vibrator theory and by means of the n-k egg-shape curve and n-k half-circle graph of reflectivity for vibrators, the influence of high-frequency dielectric constant on crystal reflection spectrum is analyzed. It is pointed out that the materials, of which the high-frequency dielectric constants are small, are advantageous to the formation of a wide low-reflectivity region in their reflection spectrum when their damping constants and oscillator strength are constant. Thus they can serve as infrared wave-absorbing material.
