fig. 1. (a) schematic of mims platform with liquid flowing through from the inlet to the outlet under the irradiation of ey-polarized thz waves; (b) tri-layer structure of the mims platform; (c) photograph of real mims device; the clamp and screws are used to package the layer materials and the soft pipes to guide the fluids. (d) optical microscopy image of fabricated srrs in a certain region; (e) geometric configuration of srrs.

mg游戏大厅fig. 2. (a) measured thz transmission spectra for the mims sample showing the modulation of resonant peaks with varying water content from 0% to 100%; (b) corresponding simulation spectra, whereby the increasing water content levels are represented by an increasing water-layer thickness together with the enhancement of ipa-layer permittivity. (c) schematic illustration of simulated model, in which the water layer and ipa layer are created to simulate the water effect in reality; (d) parameters extracted from the coupled lorentz oscillator model by fitting the experiments in the frequency range marked as gray in (a) under different water contents; (e) electric field monitored to srrs under 0.2 and 2 μm water-layer thickness at three resonant peaks marked as i, ii, and iii in (b), respectively.

fig. 3. (a)–(d) joint time-frequency analysis of experimental extinction obtained from cwt at water content of (a) 0%, (b) 20%, (c) 60%, and (d) 100%. (e), (f) the dependences of extinction intensity and fwhm of gaussian curve acquired at 2.21 thz on water content at (e) position 1 and (f) position 2 that have been marked in (a).

fig. 4. (a)–(c) dependence of measured transmission on frequency and water content in (a) ipa, (b) ethanol, and (c) acetone. (d)–(f) dependence of measured phase shift on frequency and water content in (d) ipa, (e) ethanol, and (f) acetone. (g)–(i) group delays under different water contents in (g) ipa, (h) ethanol, and (i) acetone. (j)–(l) corresponding transmission and phase shift of three peaks labeled as peaks i, ii, and iii [as shown in fig. 2(b)] at different water contents in (j) ipa, (k) ethanol, and (l) acetone. (m) histogram of modulation depth and phase difference of peaks i, ii, and iii in different organic liquids.
