Most calibration schemes for reflection-based tissue spectroscopy in the mm-wave/ THz-frequency range are based on homogenized, frequency-dependent tissue models where macroscopic material parameters have either been determined by measurement or calculated using effective material theory. However, as the resolution of measurement at these frequencies captures the underlying microstructure of the tissue, we will investigate the validity limits of such effective material models over a wide… 
The Importance of Subcellular Structures to the Modeling of Biological Cells in the Context of Computational Bioelectromagnetics Simulations
TLDR
A method is presented here to determine the current and power densities occurring in single cells and their distinct compartments in a spatially accurate manner as a first step towards multicellular models within the microstructure of tissue layers.

Human skin permittivity determined by millimeter wave reflection measurements
TLDR
Millimeter wave reflection from the human skin was studied in the frequency range of 37-74 GHz in steps of 1 GHz to determine the complex permittivity and water content of skin layers and the fitting parameters obtained were consistent with each other.
