Abstract

Terahertz (THz) radiation in the infrared region of electromagnetic spectrumhas a frequency
range close to water molecular frequency. Interaction of THz radiation indicates a low
scatteringabsorption. This study examines the modeling of one cycle THz wave radiation on
biological tissues such as skin tissue, fat, tumor, and beef by focusing on the physical
parameters of electromagnetic waves Maxwell's Equations. The solution ofthis study uses
computational methods with Wolfram Mathematica 9.0 software to use sources of THz power
density (10-150) mW.m-3 and a frequency range (0.1-1) THz. The quality of the absorption
spectrum of THz radiation is limited by the resolution of the resonance frequency varies. At
lower resolutions, the peak of the spectrum is expanded by the energy level can be
determined with high accuracy. There are differences of peaks between tumor tissue and
normal tissue. This can be seen with the absorption models and experimental results indicate
quite accurate with an error of 0.8%.
