相干完全吸收:电磁学观点

Coherent Perfect Absorption: an electromagnetic perspective

Sanjeeb Dey, Suneel Singh

摘要:

通过电磁波处理和界面边界条件,给出了确定相干完全吸收条件的一个简单封闭表达式。除了提供物理洞察力,该表达式可以用来估计所需的各种参数的值,在一个给定的介质中,其特征在于由复介电常数的相干完美吸收的观察。理论表达式的结果被发现是通过数值模拟得到的那些很好的协议。

英文摘要:

We present a simple closed expression for determining the condition for Coherent Perfect Absorption derived through electromagnetic wave treatment and interface boundary conditions. Apart from providing physical insight this expression can be used to estimate the values of various parameters required for observation of coherent perfect absorption in a given medium characterized by a complex dielectric constant. The results of the theoretical expression are found to be in good agreement with those obtained through numerical simulations.
