Estimation of human-hemoglobin using honeyb structure:An application of photonic crystal
abstract
This paper proposes a method to estimate the hemoglobin concentration in human blood using 2D honeyb photonic crystal structure. Though a few works deal with similar kind of investigation, presentresearch delivers an accurate estimation of hemoglobin as pared to previous works. The principleof investigation is based on linear variation of both photonic band gap and absorbance’s with respect to different concentration of hemoglobin in human blood. Aside these variations, energy transmittedthrough honeyb photonic crystal structure is also varied linearly with respect to same this work, photonic band gap of honeyb structure is found using plane wave expansion method,whereas absorbance of same structure is puted by employing Maxwell Curl equation. Finally, simulation result revealed that transmitted energy through two dimensional honeyb photonic crystalstructure containing blood is nicely fitted with linear trend line (R2 = 1) which lead to an accurate investigation of hemoglobin in human blood. At last, this paper proposes an experimental set up to measurethe said concentrations with the help of an Arduino developmentboard(Uno)containingAtmega320microcontroller.

Introduction
Photonics crystals are made, artificially created materials inwhich refractive index is periodically modulated in a scale parable to the scale of the wavelength. Though the concept ofphotonic crystal has originated in the year 1857 by Lord Rayleigh,the research work in the field of photonic crystals is realized afteralmost 100 years, when Yablonovitch and John published twomilestone papers on photonic crystals in 1987 [1–3], since
