# Carbon Nanotubes as base Material for Fabrication of Gap Waveguide Components

Research arti­cle pub­lished in EUROSENSORS 2014, the 28th Euro­pean Con­fer­ence on Sol­id-State Trans­duc­ers. Abstract: Car­bon nan­otubes are being used here as a base mate­r­i­al for rapid pro­to­typ­ing of a high fre­quen­cy device. It has been imple­ment­ed on a ridge gap res­onator for 220–325 GHz which has pre­vi­ous­ly been fab­ri­cat­ed in Si. Micro­fab­ri­ca­tion with Si has its ben­e­fits but it is time con­sum­ing when etch­ing high ratio struc­tures. CNT based struc­tures offer a rapid and low cost turnover for pro­to­typ­ing. Mea­sure­ments com­par­ing the CNT-based struc­ture to a pre­vi­ous­ly made Si struc­ture and sim­u­la­tions are pre­sent­ed. The unloaded Q‑values and the loss/​mm are pre­sent­ed from sim­u­la­tions, Si-based res­onator mea­sure­ments and CNT-based res­onator measurements.
