Data supporting the publication "Anomalous resonance frequency shift in liquid crystal-loaded THz metamaterials".

This data supports the figures presented in the article: "Anomalous resonance frequency shift in liquid crystal-loaded THz metamaterials" published in 2022 in Nanophotonics The data supports the information we have discovered as part of the design of MMs we chose for our study. The design was based on a D-shaped metamolecule (see data for Figure 1(a)) – a derivative of the asymmetrically-split ring resonator, which in the past had enabled the engineering of high-Q Fano resonances in MMs and served as a building block for one of the first MM-based sensing platforms. The two Babinet complementary patterns of the MMs featured arrays of such metamolecules formed, respectively, by metal patches (positive MM) and slits in a metal screen (negative MM). This dataset contains data which are used for generating Fig.1a, Fig.2a-c, Fig.3b, and Fig.3d. These figures are plotted using basic plotting software such as Matlab, Origin, Excel, etc. The figures are as follows: Fig. 1a Transmission spectra measured experimentally (open triangles) and simulated (thick solid lines) for pristine MMs of positive (red) and negative (blue) designs. Fig. 2a Calculated maximum resonance shift that can be attained in positive (black points) and negative (red points) MMs at different values of LC birefringence. Fig. 2b Transmission spectra measured experimentally (open triangles) and simulated (thick solid lines) for negative MM loaded with NLC in planar 1 (red) and planar 2 (blue) configurations. Fig. 2c Same as 2b but for positive MM. Fig. 3b Transmission spectra measured experimentally (open triangles) and simulated (thick solid lines) for positive MM taking into account the effect of orientation nonlinearity of NLC in planar 1 configuration. Fig. 3d Same as 3b but for initial planar 2 alignment of NLC.
