蜂巢构造仿生研究与应用
学院名称:京he field of photonic crystals is realized afteralmost 100 years, when Yablonovitch and John published twomilestone papers on photonic crystals in 1987 [1–3], since then,photonics have been progressing hastily and showing a remarkableresearch in the field of science and technology. As far as, application of photonic-devices are concerned, photonic crystal play animportant role to envisage various application in modern technology [4–6]. Though photonic crystal is used for different application,sensing application is one of the major relevance in photonics. As faras literature surveys on sensing application using photonic crystalstructure is concerned, recently few papers deal with similar typeof research [7–13]. Considering a brief remark on above references,it is seen that reference [7] presents a novel method to find out theconcentration of sugar, salt, and alcohol in their aqueous this case, the author used 2D photonic crystal structure with11 × 11 air using same technique, concentration of PAMhydrogel and strength of Cygel is investigated in Refs. [8,9], respectively. Also in Refs. [10,11], the concentration of potassium chloridein their aqueous and intrallipid in human blood is estimated usingphotonic crystal fiber. Apart from these, measurement of glycerolin B–H–G solution and concentration of hemoglobin in humanblood is investigated using 3D photonic crystal structure in Refs.[12,13], respectively. Though Ref. [13] measures the concentrationof hemoglobin in human blood using 3D photonic crystal structure,it is hard to fabricate 3D owing to photonic crystal structure. We inthis paper investigate the concentration of hemoglobin in humanblood using 2D honeyb photonic crystal structure. The reasonfor choosing such structure is that it can be easily fabricated; secondly, these structures predict accurate result as pared to 3D
