Abstract
We propose a photonic crystal fiber with circular air pores of 400 nm in dimension to evaluate urea concentration in human blood. When the structure excited with a signal of 590 nm, the refractive index subjected to change for blood samples which in result exhibit the varying electric field at the output. This variation decides the amount of urea content in the sample. The plane wave expansion (PWE) method is explicitly adopted in finding the required scattering field in the photonic crystal structure. It is interesting to note that the transmitted light varies linearly as a function of amount of concentration of urea filled within the air gaps.
