对二维光子晶体的电磁波理论及周期性介质中的Bloch波解做了详细的推导,给出了光子晶体中的禁带存在的理论依据,同时以三角晶格的二维光子晶体为例,采用平面波展开方法对果糖水溶液的浓度进行测定。主要利用硅与果糖溶液介电常数较大的原理,通过数值模拟获得相应的光子禁带图并加以分析。结果表明,以果糖的水溶液作为空气圆孔中的介质材料,当溶液浓度不同时TE模式的光子禁带(PBG)明显变宽,而TM模式不出现光子禁带现象。研究结果及方法对高血糖临床应用有一定的指导作用。
The theory of electromagnetic waves in two-dimensional photonic crystals and the Bloch wave solutions in periodic media are deduced in detail, and the theoretical basis for the existence of the forbidden band in photonic crystals is given. Taking the two-dimensional photonic crystal of triangular lattice as an example, The concentration of fructose aqueous solution was determined by plane wave expansion method. The main use of silicon and fructose solution larger dielectric constant principle, obtained by numerical simulation of photon band gap diagram and analysis. The results show that the photonic band gap (PBG) of TE mode broadens obviously when the aqueous solution of fructose is used as the dielectric material in the air hole, and the photon band gap does not appear in the TM mode. The results and methods for the clinical application of hyperglycemia have a certain guiding role.
