Noble metal nanoparticles possess extraordinary optical properties due to their plasmon modes that make them desirable for inclusion into materials. Non-dipolar plasmon modes are one of the simplest known ways to control the magnetic properties of a material; consequently gold nanoparticles are one of the most promising systems to produce metamaterials. In order to fully utilize the properties of gold nanoparticles for device applications, one needs to control the interparticle spacing, distribution, and orientation of anisotropic gold nanoparticles within a material. Liquid crystalline host materials can allow for alignment and self-assembly of nanoparticles through viscoelastic forces. In this thesis, I ...
