Abstract

Abstract To obtain radiation pressure of a hybrid chiral structure, we derive the transfer matrix method and optical force densities from the Maxwell stress tensor for a planar layered bianisotropic media. The key derivations are how to get wavevectors and field components of each layer, transfer matrices connecting four eigenwaves of adjacent chiral media, as well as the force densities expressed by co- and cross-polarized reflection and transmission coefficients. After the validation of the methods and programs is performed, the radiation pressure of a layered biaxial bianisotropic chiral slab is studied. The effects of linearly and circularly polarization incident waves, incident angle, thickness, opposite handedness (optical activity), anisotropy, gain and loss of chiral media on the radiation pressure are discussed. Our work elucidates the mechanism of light-chiral media interactions, provides better understanding of chiral detection, optical trapping, and biophysics.

杂化双各向同性手性结构的辐射压力
摘要为了获得混合手性结构的辐射压力,我们从平面层状双各向同性介质的Maxwell应力张量中导出了传递矩阵方法和光力密度。关键的推导是如何获得每层的波矢量和场分量,连接相邻手性介质的四个本征波的传递矩阵,以及用共极化和交叉极化反射和透射系数表示的力密度。在对方法和程序进行验证后,研究了层状双轴双各向同性手性平板的辐射压力。讨论了线性和圆偏振入射波、入射角、厚度、反手性(光学活性)、各向异性、手性介质的增益和损耗对辐射压力的影响。我们的工作阐明了光-手性介质相互作用的机制,更好地理解了手性检测、光学捕获和生物物理学。

期刊介绍: Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal. Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies. RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
