Recently published Radiometric measurements of human subjects in the frequency range 480-700 GHz, demonstrate the emission of blackbody radiation from the body core, rather than the skin surface. We present a detailed electromagnetic simulation of the dermis and epidermis, taking into account the presence of the sweat duct. This complex structure can be considered as an electromagnetic bio-metamaterial, whereby the layered structure, along with the topology of the sweat duct, reveals a complex interference pattern in the skin. The model is capable of accurately representing the skin greyness factor as a function of frequency and this is confirmed by radiometry of living human skin.
最近发表的在 480-700GHz 频率范围内对人体受试者的放射性测量结果表明，人体核心会发出黑体辐射，而不是来自皮肤表面。我们提出了一种详细的表皮和真皮的电磁模拟，考虑到了汗管的存在。这种复杂的结构可以被视为一种电磁生物超材料，其中分层结构以及汗管的拓扑结构在皮肤中呈现出复杂的干涉模式。该模型能够准确地表示皮肤灰度因子随频率的变化，这一点通过对活体人体皮肤的辐射测量得到了证实。
