With the advances in 5G technology and the future development of potential 6G operating systems, there is growing anticipation for higher frequencies reaching up to 4 THz in the electromagnetic (EM) spectrum. With the increase in frequency, reaching significantly beyond 6 GHz, the penetration depth decreases, resulting in a more significant deposition of EM energy within superficial tissues with a high water content, such as the cornea. In this study, we analyzed the power density and electric field distributions and the resulting temperature rise in the cornea when exposed to plane waves ranging from 30 GHz to 0.5 THz. Our findings indicate that the impact of mmW and THz radiation on the cornea may be slightly more noticeable in the case of dry eyes. However, further investigation is needed through in vivo studies to gain deeper insights into these effects and their potential implications.
