摘要

本文基于生物组织在千兆赫和太赫兹频率下的电磁特性，分别推导了Debye介质的时域有限差分(FDTD)算法。在每个条带中，模拟了两种典型的生物组织。通过癌组织与皮肤组织的对比，可以得出癌组织对电磁波的吸收率要优于皮肤组织。此外，模拟实验可以让我们观察到电磁波在生物组织中的传播，这可以帮助研究人员分析和理解电磁波在癌症检测和治疗中的理论。

Theory of tissue detection based on FDTD algorithm

In this paper, based on the electromagnetic properties of biological tissue in the gigahertz and terahertz frequency, we deduced the finite difference time domain (FDTD) algorithm for Debye media respectively. And in each of the two bands, two kinds of typical biological tissues were simulated. By comparing the cancer tissue with skin tissue, it can be drawn that the absorption rate of electromagnetic wave for cancer tissue is better than that of skin tissue. In addition, simulation experiments allow us to observe the propagation of electromagnetic waves in biological tissue, which can help researchers analyze and understand the theory of electromagnetic wave in cancer detection and treatment.
