Wave propagation in a dielectric rod waveguide loaded with a layer of silver nanowires was studied experimentally at millimeter wave frequencies. Then based on the measurement results, analytical calculations were used to estimate conductivity of the silver nanowire layer at millimeter wave frequencies. Numerical simulations based on the calculated conductivities were performed and good agreement...
Resonator techniques for precise measurements of gazes and condensed media in wide frequency range from 40 GHz up to 500 GHz and in the temperature interval from 4 K up to 900 K are presented. The measurement methods are the absolute ones and self “calibrated” it means that it is not necessary to use the prior information. Concrete values are calculated from the measured of the resonator frequency...
To ensure the high performance of graphene-based field effect transistors (GFETs) on flexible substrates, an uniform and manufacturable dielectric film with good electrical properties is needed. Thus, electrical characterization of the dielectric film on graphene on flexible substrates is very important for the development of flexible electronics based on GFETs. Here, we have fabricated and characterized...
