Setup for Material Characterization in the 110-170 GHz Band Moreno Rodríguez, Salvador Pérez Escribano, Mario Ortiz Ruiz, Sergio Ruiz, Francisco G. Plaza Gallardo, Borja Molero, Carlos Márquez Segura, Enrique This work outlines the procedure to establish a system for assessing materials’ complex permittivity and permeability within the 110-170 GHz frequency range. We present the employed methodology and the calibration procedure for the system, incorporating a dual approach using TRL (Thru- Reflect-Line) and GRL (Gated-Reflect-Line) methods. Following that, a smoothing technique is used to enhance the accuracy of the results. Tests were conducted on a HIPS sample to validate the system’s performance, demonstrating the results’ reliability across the entire measured bandwidth. 2025-02-25T11:01:25Z 2025-02-25T11:01:25Z 2024 journal article S.
