摘要

我们比较了计算双曲型超材料中Purcell因子的两种模拟方法，并通过测量验证了我们的模拟结果。我们通过直接计算周期单元胞带结构的局部态密度来计算Purcell因子。我们将此方法与结构内偶极子天线阻抗的时域有限差分(FDTD)计算得到的Purcell因子进行了比较。我们证明了可以用电偶极子和磁偶极子来研究横向电(TE)和横向磁(TM)极化中的Purcell因子，并通过分析结构的色散关系来支持我们的论点。

Evaluating the Purcell factor in hyperbolic metamaterials

We compare two simulation methods of calculating the Purcell factor in a hyperbolic metamaterial and validate our simulations with measurements. We calculate the Purcell factor from a direct calculation of the local density of states from the band structure of the periodic unit cell. We compare this method with calculations of the Purcell factor obtained from the finite difference time domain (FDTD) calculations of the impedance of a dipole antenna located inside the structure. We show that we can study the Purcell factor in transverse electric (TE) and transverse magnetic (TM) polarisations by using electric and magnetic dipoles, we support our argument by analysing the dispersion relations of the structure.
