The characteristics of photonic crystal made of LHM and RHM with an imaginary part of dielectric constant 复介电右手材料和左手材料构成的光子晶体的特性研究
The large transmittance gains appear at transmittance peaks if the imaginary part of dielectric layer's dielectric constant is negative. 随着复介电常量的虚部的增加,两透射增益先增加后减少,中间存在一极值点。
A minimum of the imaginary part of the dielectric constant was observed at lower frequencies from the frequency dependence of the dielectric constant, this implies the existence of imperfections and space-charge polarization in the crystals. 介电系数的频率特性显示,介电系数虚部在较低频率时呈现极小值,这表明晶体中存在缺陷和空间电荷极化。
The loss is greater when the imaginary part of the complex dielectric constant is bigger and the mode order is higher. 介电常数虚部大(绝对值),而且包层模序也大时,损耗较大。
The real-part signal produced by the drill collar in the earth can be approximately regarded as constant, and the imaginary part can also be approximately regarded as constant when the conductivity of the earth is greater than 0.01S/m. 钻铤在地层中产生的实部信号可近似认为恒定,而当地层电导率大于0.01S/m时,钻铤在地层中产生的虚部信号亦可近似认为恒定。
Soil type has little influence on imaginary part of dielectric constant. 土壤类型和介电常数虚部几乎没有相关性。
