We experimentally demonstrate resonantly enhanced nonlinear optical processes such as 2nd-, 3rd-, and 4th-harmonic generations, sum-frequency generation, four-wave mixing processes, etc., in the visible and near-IR using GaAs dielectric metasurfaces.
In this paper we introduce a bottom-up microwave and millimeter wave modeling strategy for membrane bound biological systems. The approach is based on the stepwise integration of bulk liquid and membrane dielectric spectroscopy data into 3D biophysical models that are amenable to efficient electromagnetic computation. The purpose of this modeling effort is to develop more understanding of microwave...
This paper presents a calibration method for broadband dielectric spectroscopy of micro-liter samples of biological liquids with transmission line sensors up to 110 GHz. The method uses water and methanol as calibration liquids to perform a probe-tip-to-liquid calibration without prior knowledge of their complex permittivity. Extracted complex permittivities of the calibration liquids show good agreement...
This paper reports on dielectric spectroscopy for microliter liquid samples using reference materials. In order to fully determine the calibration coefficients, air and water are used as known reference materials, while methanol is used as an unknown material, which is also used to validate the approach up to 5 GHz for which reference data is available. The method is then used up to 110 GHz for yeast...
