Design and Analysis of HPCF Sensor Model for Different Milk Sensing

Nowadays photonic crystal fiber is used for sensing liquid and solid materials. Here we used Hexagonal photonic crystal fiber (HPCF) for different animal's milk sensing. Water, Camel Milk, Buffalo Milk, Cow Milk and Goat Milk are injected in core region one by one as sensing liquid and studied various sensing properties like external refractive index (ERI), Birefringence, comb-like profiled fiber (CPF), A
eff
, Nonlinearity and Relative Sensitivity. The HPCF performance studied for different Parameters according to parameter when pitch is 7 micrometer to 10 micrometer and used various liquid, water, camel milk, buffalo milk, cow milk, goat milk respectively and for frequencies range 1.0 THz to 3.0 THz. When
$\mathrm{f}=1.5$
THz, the relative sensitivity is studied 90.425%, 90.796%, 90.949%, 90.613% and 90.607% for Water, Camel Milk, Buffalo Milk, Cow Milk and Goat Milk respectively and when
$\mathrm{f}=2.5$
THz, the relative sensitivity is studied 92.329%, 92.891%, 93.243%, 92.513% and 92.587% for Water, Camel Milk, Buffalo Milk, Cow Milk and Goat Milk respectively. We found 179137 micrometer
