高斯光束在复合介质中的相干完全吸收研究

Study of Coherent Perfect Absorption Using Gaussian Beam in a Composite Medium

Sanjeeb Dey

摘要:

研究了金属-介质复合介质中的相干完全吸收效应。CM是一种正交形状的平板,由两束相同的高斯光束(GB)以相等的入射角入射,并从相对侧聚焦在平板壁与空气之间的两个界面上。确定了CPA所需的必要条件,并证明了完全CPA是可能的。作者还表明,较宽的光束表现出更多的吸收比比较紧聚焦光束。

英文摘要:

There is a study of coherent perfect absorption (CPA) in composite medium (CM) which is made of metal-dielectric composition. The CM, an orthorhombic shaped slab, is illuminated by two identical Gaussian beams (GB) incident at equal angle of incidence and focused on the two interfaces between wall of slab and air from opposite side. It has determine the necessary conditions required for CPA and shows that perfect CPA is possible with GBs. Author also shows broader beams exhibit more absorption than comparatively tightly focused beams.
