11. Dual-polarized geodesic lens in sub-THz
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In the sub-THz frequency range, the geodesic lens can realize low losses and beam scanning capability with high gain and high aperture efficiency due to its fully metallic property and rotational symmetry. Therefore, in high-frequency applications, a geodesic lens is considered a more promising solution in comparison to phased arrays or other beamforming techniques. READ MORE

12. Dual-polarized fully-metallic Vivaldi antenna array in a triangular lattice
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : New mobile communication generations need electromagnetic sensors capable of steering their high-directive beams towards the users. Conventional base stations use square lattice phased arrays to accomplish this task. These arrays are composed of a large number of radiating elements to achieve the required high directivity and scanning capabilities. READ MORE

13. Nonlinear mode coupling and parametric amplification with superconducting kinetic inductance
University essay from KTH/Tillämpad fysikAbstract : We investigate the resonant characteristics of superconducting meandering nanowires to design a nonlinear kinetic inductance traveling-wave parametric amplifier. The devices are patterned out of 15 nm thick NbTiN films. They consist of a coplanar waveguide, that shrinks into 100 nm wide meandering nanowires. READ MORE

14. Design of Autonomous Underwater Vehicle’s (AUV) Antenna System
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The ocean symbolizes mystery, passion, and power. However, most of the ocean, about 80 %, is unknown to humans. AUVs (Autonomous Underwater Vehicles) provide a platform where terrain mapping, the biodiversity, and the resource survey of the ocean become accessible. READ MORE
