Abstract
In this Letter, a completely ferrodielectric metasurface consisting of an array of cylinders on a substrate is studied. All structural elements are made of ferrodielectric material. The conditions for the excitation ofWood's anomaly mode, obtained for different geometric parameters of the metasurface, are revealed. By continuously changing the structure parameters, we can change the position of the resonance at the Wood anomaly, thereby setting the position of the resonance at the frequency we need. It is shown that there is a resonant increase in the polarization plane rotation of the transmitted waves at the corresponding resonant frequency of the lattice mode excitation. Such polarization rotation is demonstrated both experimentally and theoretically.
