This paper presents a new method for the determination of the complex permittivity of thin sheet dielectric materials that are flexible and elastic. Instead of the traditional method to install a doughnut shape sample in the transverse plane used in transmission line methods, most widely used methods for broadband permittivity measurements, a thin sheet sample is installed onto the outer conductor...
In this paper we present the novel design of a microstrip sensor to measure the broadband complex permittivity of small fluid samples and accurately predict their Cole-Cole parameters. This novel approach differs from prior works by placing the fluid analyte in an enclosed chamber underneath the trace of a suspended microstrip, allowing for better overlap between the electromagnetic fields and the...
This paper explores building planar transmission lines using carbon nanotube (CNT) networks. Transmission lines with carbon nanotube networks replacing the conventional metallic traces are presented. The experimental realization and the repeated two-port microwave measurements of the proposed transmission lines enable accurate extractions of the fundamental parameters showing percolation effects in...
In this paper, we explore building planar transmission lines using carbon nanotube (CNT) networks. We are successful in building the transmission lines and verifying the feasibility of potential planar transmission lines where carbon nanotube networks replace the conventional metallic traces. The experimental realization and the two-port microwave measurements of the proposed transmission lines enable...
