The design of a minimally invasive surgery tool for the detection and treatment of cancerous tissue is presented. The planar structure is based on spiral resonators, with an operating frequency range from 4 GHz to 6 GHz, excited by a conventional coplanar waveguide to, firstly, extract resonance shifts to gain information about permittivity changes in the surrounded tissue. As second feature, tumorous...
In this work, the first broadband dielectric characterization of African trypanosome parasites from 0.2 to 2.5 THz is presented as a foundation for future sensor applications in the mm- and THz-wave regime. After demonstrating detectability, the complex permittivity of a 5 micrometer thick parasite film is extracted directly from measurements of a terahertz time domain spectrometry setup using a chain...
