Paper Abstract

We demonstrate that to form a high-intensity THz terajet (field localization) within the graphene monolayer placed at the shadow surface of one wavelength-dimensions dielectric particle with refractive index near 2 the cubic shape is preferable in comparison with spherical one. A spherical particle is more magnetic than electric due to multipole mode distributions. A graphene monolayer was applied for a picosecond timescale modulation of THz wave by controlling of IR radiation for integrated ultrafast all-optical THz modulator. Application of biological objects to the shadow surface of the mesoparticle instead of graphene will allow studying the biophysical aspects of the interaction of the electromagnetic field with such biological objects.
