READ ME File For Experimental and Simulated Data Dataset DOI: 10.5258/SOTON/D2178 ReadMe Author: Eleni Perivolari, University of Southampton This dataset supports the publication: Anomalous resonance frequency shift in liquid crystal-loaded THz metamaterials. Contents This dataset contains 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.
