摘要

具有亚波长圆柱形孔隙的介电材料的光学特性通常用有效介质模型来描述。我们将多孔硅的麦克斯韦-加内特（Maxwell Garnett）和布鲁格曼（Bruggeman）有效介质模型与偏振与孔轴正交情况下的模拟和实验进行了比较。即使孔隙率非常高，麦克斯韦-加内特模型也能与模拟结果相匹配。通过分析长波长极限的法布里-佩罗特振荡，对大孔和介孔硅的有效介电常数进行了实验研究。这些实验结果也与麦克斯韦-加内特模型一致。我们主张今后将该模型用于具有圆柱形孔隙的介质。

On the applicability of the Maxwell Garnett effective medium model to media with a high density of cylindrical pores

The optical properties of dielectric materials with subwavelength cylindrical pores are commonly described by effective medium models. We compare the Maxwell Garnett and the Bruggeman effective medium models for porous silicon with simulations and experiments for the case of polarization orthogonal to the pore axis. The Maxwell Garnett model matches the results of the simulations even up to very high porosities. An experimental study of the effective permittivity of macroporous and mesoporous silicon is conducted by analyzing the Fabry-Pérot oscillations in the long-wavelength limit. These experimental results are also consistent with the Maxwell Garnett model. We advocate using this model for media with cylindrical pores in the future.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optical Materials Express (OMEx), OSA''s open-access, rapid-review journal, primarily emphasizes advances in both conventional and novel optical materials, their properties, theory and modeling, synthesis and fabrication approaches for optics and photonics; how such materials contribute to novel optical behavior; and how they enable new or improved optical devices. The journal covers a full range of topics, including, but not limited to: Artificially engineered optical structures Biomaterials Optical detector materials Optical storage media Materials for integrated optics Nonlinear optical materials Laser materials Metamaterials Nanomaterials Organics and polymers Soft materials IR materials Materials for fiber optics Hybrid technologies Materials for quantum photonics Optical Materials Express considers original research articles, feature issue contributions, invited reviews, and comments on published articles. The Journal also publishes occasional short, timely opinion articles from experts and thought-leaders in the field on current or emerging topic areas that are generating significant interest.
