In this paper, a decagonal geometry has been designed for liquid sensing. The liquid analytes that are sensed are ethanol, benzene and water as they are the most used analytes in the chemical and biological industries. Firstly, a decagonal structure has been designed and n_eff and sensitivity of this structure has been calculated. Then, the core structure has been modified and decagonal, octagonal and hexagonal geometries have been constructed inside the core with circular holes. Lastly, these circular holes have been replaced by elliptical holes. All the designed layouts have been analyzed and compared. The sensitivity obtained is of the order 40-50 % and confinement loss of order 10^-9 dB/m which shows that these structures can be used for sensing ethanol, water and benzene and are reliable. For benzene, water and ethanol, the decagonal structure with core comprised of decagonal geometry, has been made of elliptical holes (x as major axis), gives the best results. For this geometry, the n_eff values are 1.379, 1.317 and 1.313 for benzene, ethanol and water, respectively. The sensitivity values obtained are 51.94%, 46.95%, and 44.45% and confinement loss value is 8.19 x 10^-10, 1.03 x 10^-10 and 1.069 x 10^-7 dB/m, respectively.

椭圆形气孔十边形光子晶体光纤的设计与分析

在本文中，已经设计出用于流体感测的十边形几何形状。被检测到的液体分析物是乙醇，苯和水，因为它们是化学和生物工业中最常用的分析物。首先，设计了十边形结构，并计算了该结构的n _eff和灵敏度。然后，对芯结构进行了修改，并在具有圆形孔的芯内部构造了十边形，八边形和六边形几何形状。最后，这些圆形孔已被椭圆形孔代替。已对所有设计的布局进行了分析和比较。获得的灵敏度约为40-50％，限制损耗约为10 ^-9 dB / m表明这些结构可用于感测乙醇，水和苯，并且可靠。对于苯，水和乙醇，以椭圆形孔（x为长轴）制成的具有十边形几何形状的核的十边形结构具有最佳效果。对于这种几何形状，苯，乙醇和水的n _eff值分别为1.379、1.317和1.313。所获得的灵敏度值是51.94％，46.95％，44.45和％和禁闭损耗值是8.19×10 ^-10，1.03×10 ^-10和1.069×10 ^-7 分贝/米，分别。
