微圆柱的局域模密度

The Micro-cylinder's Local Density of Modes

本文利用微圆柱的分立电磁场模计算了有泄漏的微圆柱腔的局域膜密度。并利用所得结果对微圆柱的模密度进行了数值计算，从而说明了微圆柱轴向和横向模谱的不同。由此我们可以知道微圆柱在散射、热辐射谱、以及形貌共振等实验中都具有空间不均匀性和方向性。

:In this paper,We get the microcylinder's local density of modes and use the result for the mathematical calculation of microcylinder's density of modes.Characters were different between the Zaxis and the Z's perpendicular axis.We can know that the microcylinder's characters are dependent of the space and orientation in the experiment of scattering、thermal spectrum、morphologydependent resonance.
