In this tutorial you will learn how to use Gaussian beam sources to illuminate non-dispersive and dispersive material blocks. You will also generate a fixed-cell mesh for your project and set up time-domain animation of the fields propagating inside the material blocks. In the first part of the tutorial lesson, you will consider a non-dispersive dielectric material. In the second part, you will work with a left-handed metamaterial and will explore the effect of a doubly negative refractive index on the beam propagation.
