1. 1. Beam Steering Antenna Based on Continuous Transverse Stub Array and Flat Risley Prism Metasurface Lens

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Carl Henriksson; Jonathan Fransson; [2023]
   Keywords : ;

   Abstract : Satellite communication is an integral part of society in this day and era. Due tobandwidth limitations communication frequencies have moved into higher frequencybandwidths. With the advancements in communication comes the demand for more efficientantennas due to the high attenuation of millimeter wavelength frequencies. READ MORE

3. 2. Real- and Quasi-Atomic Layer Etching for Ultra-High Resolution Patterning

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Yoana Ilarionova; [2023]
   Keywords : Physics and Astronomy;

   Abstract : An attempt was made at developing atomic layer etching from a cyclic etching process in an ICP-RIE tool. During the process OES was used for contamination monitoring and estimation of the relative amount of Cl2 left in the chamber during the etch step of cyclic etching processes. READ MORE
