Terahertz Field Confinement in Nonlinear Metamaterials and Near-Field Imaging

This article reviews recent advances in terahertz science and technology that rely on confining the energy of incident terahertz radiation to small, very sub-wavelength sized regions. We focus on two broad areas of application for such field confinement: metamaterial-based nonlinear terahertz device...
