Design and Analysis of Optical Fiber Probes for Glucose Sensing in the Peritoneal Cavity
Walmsness, Per Magnus (Master thesis, 2016)This thesis is focused on the design and analysis of optical fiber probes for glucose sensing in the peritoneal cavity. The probes are to be used as absorption cells for near-infrared absorption spectroscopy of peritoneal ... -
Dispersion of resonant modes in patch antenna lattices
Kildemo, Morten; Walmsness, Per Magnus; Hale, Nathan (Journal article; Peer reviewed, 2022)Spectroscopic polar angle resolved Mueller matrix ellipsometry at multiple azimuthal incidences, together with a full-field model, reveal new details in the interplay between localized gap surface plasmon resonances and ... -
Optical response of rectangular array of elliptical plasmonic particles on glass revealed by Mueller matrix ellipsometry and finite element modeling
Walmsness, Per Magnus; Brakstad, Thomas Vågenes; Svendsen, Brage Bøe; Banon, Jean-Philippe Armand; Walmsley, John; Kildemo, Morten (Peer reviewed; Journal article, 2019)We report here on the optical response of elliptical gold particles arranged in a rectangular lattice on glass and probed at non-normal incidence in reflection using spectroscopic Mueller matrix ellipsometry in the energy ... -
Spectroscopic Mueller matrix ellipsometry of a gap surface plasmon array at conical incidences
Walmsness, Per Magnus; Hale, Nathan; Kildemo, Morten (Peer reviewed; Journal article, 2021)Spectroscopic Mueller matrix ellipsometry is used to study an array of rectangular Au patches on a SiO2 film backed by optically thick Au. The array supports resonances related to gap surface plasmons and Rayleigh anomalies, ...
