Abstract:

In the project, we propose to incorporate liquid crystals LCs into structures containing metamaterials MMs, as one possible way of solving the challenging problem of their optical tunability. The objectives of the project are to develop the physics background and mathematical techniques enabling the evaluation of the effective electromagnetic parameters of the LC based metamaterials and study the possibility of tuning their optical properties. Configurations studied include MMs with nanoparticles or nanowires of core-shell type placed in isotropicanisotropic LC matrix, layered structures of 2D conducting materials with dielectric LC layers, or structures with LCmetallic nanostrip gratingdielectric configurations. We predict the complex dielectric function, effective permittivity tensors, and optical properties of several configurations of these systems and demonstrate tunability by changing parameters of the system.
