Another emerging application is related to THz-induced bioeffects, which were mediated primarily through photothermal mechanisms, i.e., thermal effects. [PERSON] et al. [15] derived the analytical solution for the [PERSON]'s heat equation based on a static (steady-state) model, and showed that heating efficiency is about 40% if THz radiation heats the top layer of the water disc. [PERSON] et al. [16] investigated the biological effects associated with human dermal fibroblasts exposed to 2.52 THz radiation. [PERSON] et al. [17] calculated the terahertz heating effects in realistic tissue (brain and breast tissue). [PERSON] et al. [18] analyzed the transient skin heating induced by terahertz radiation. [PERSON] et al. [19] evaluated the thermal response of human tissue exposed to a focused-beam terahertz electromagnetic radiation by solving the coupled electromagnetic-thermal problem. Encouraged by these studies, quite recently, [PERSON] et al. [20] investigated heat transfer of the eye cornea in the THz field. However, their model was relatively simple and thus insufficient to understand the transient behavior of heating effects. Questions remain, such as whether there exists thermal damage, and how THz radiation parameters influence the transient heating effect in the cornea. In this work, we theoretically investigate the thermal effects in the cornea when heated with terahertz radiation. We develop a model to describe transient temperature distributions and to evaluate the potential thermal-damage effects in the cornea heated with THz radiation. We also discuss the influence of key parameters, including the radius and power density of the THz beam.
