Tomographic measurement of dielectric tensors at optical frequency
Measuring three-dimensional dielectric tensors is desired for applications in material and soft matter physics. Here, the authors use a tomographic approach and inversely solve the vectorial wave equation to directly reconstruct dielectric tensors of anisotropic structures.
