Principles of thermal design with nematic liquid crystals
S. Fumeron, E. Pereira, F. Moraes
Highly engineered materials are arousing great interest because of their ability to manipulate heat, as described by coordinate transformation approach. Based on the recently devel…
Metric approach for sound propagation in nematic liquid crystals
E. Pereira, S. Fumeron, F. Moraes
In the eikonal approach, we describe sound propagation near to topological defects of nematic liquid crystal as geodesics of a non-euclidian manifold endowed with an effective metr…
Diffraction of light by topological defects in liquid crystals
E. Pereira, F. Moraes
We study light scattering by a hedgehog-like and linear disclination topological defects in a nematic liquid crystal by a metric approach. Light propagating near such defects feels…
On the deflection of light by topological defects in nematic liquid crystals
Caio satiro, Fernando Moraes
The influence of controlable parameters like temperature and wavelength on the trajectories of light in a nematic liquid crystal with topological defects is studied through a geome…
