Abstract

This paper presents a preliminary analysis on usage of graphene as reflect standard for vector network analyzer (VNA) calibration operating at millimeter-wave frequencies. As an example, WR03 waveguide flange is used for investigation. It is found that multilayer graphene exhibits reflection properties that makes it a suitable candidate for reflect standard to calibrate the VNA test setups operating at millimeter-wave frequencies. A parametric analysis to study the effects of graphene thickness, chemical potential and relaxation time on reflection coefficient has also been presented and discusse
