Numerical modeling of the human eye at high frequencies for wireless sensor networks

Nano-sized wireless sensor networks are IoT devices that can be widely used in the future due to their ability to easily fit inside the human body. It is aimed to be used in cases such as placing radio sensor networks in the eye, adjusting smart lenses for the eye, predicting or monitoring diseases such as eye pressure, eye trauma, eye infections. In this study, mathematical modelling of the communication characteristics of an IoT wireless device that we can place in front of the human eye at the Terahertz frequency. The main parameters to be considered in this process include the refractive index, absorption characteristics and high frequency scattering properties of the eye. The aim of this research is to contribute to the design of invisible, wearable IoT communication devices that can communicate seamlessly with the human body, which will facilitate telemedicine, remote diagnosis and related healthcare services for the device that is expected to operate with an ultra-low latency network at high frequencies. One-way communication method was used, the effect of different frequency ranges on communication performance, suggestions for optimising the interactions of communication between devices at high frequencies were given and lossless transmission data were found to be 2.30 mm (at 0.03 THz), 1.00 mm (at 0.06 THz), 1.00 mm (at 0.1 THz), 0.75 mm (at 0.2 THz) and 0.55 mm (at 0.3 THz) in order of preference for the relevant frequency.
