In the here-reported study, we investigated the dielectric properties of three different skin-mimicking materials used in the reported controlled experiments for development and testing of microwave-range medical devices. Each of the phantom materials under consideration is tested in two forms: a thicker, larger block and a 2-mm sheet. The measured properties are compared to a reference of human skin tissue measurements from literature. Depending on the frequency range of the medical device in development, some phantoms are more suitable to represent human skin than others. We observe that all phantoms still show lower dielectric properties than the human skin reference, but are suitable representations of skin at microwave applications if used as 2-mm thin layers.
在本报告的研究中，我们研究了三种不同的仿皮肤材料的介电特性，这些材料用于已报道的微波波段医疗设备开发和测试的对照实验中。所考虑的每种仿体材料都以两种形式进行测试：较厚、较大的块状和2毫米厚的薄片。将测量的特性与文献中人体皮肤组织测量的参考值进行比较。根据正在开发的医疗设备的频率范围，一些仿体比其他仿体更适合代表人体皮肤。我们观察到，所有仿体的介电特性仍低于人体皮肤参考值，但如果用作2毫米厚的薄层，则适合在微波应用中代表皮肤。
