1. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. READ MORE

2. Numerical Simulations of Resonant Tunnelling Diodes
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : In this thesis, four different numerical techniques are implemented for the purpose of simulating resonant tunnelling diodes (RTDs). The chosen methods were: piecewise constant transfer matrix (TMM-C), piecewise linear transfer matrix (TMM-L), quantum transmitting boundary method (QTBM), and the Crank-Nicolson method (CN).

3. A geometric approach to calculating the limit set of eigenvalues for banded Toeplitz matrices
University essay from Lunds universitet/Matematik LTHAbstract : This thesis is about the limiting eigenvalue distribution of n × n Toeplitz matrices as n → ∞. The two classical questions we want to answer are: what is the limit set of the eigenvalues, and what is the limiting distribution of the eigenvalues. Our main result is a new approach to calculate the limit set Λ(b) for a Laurent polynomial b, i.e. READ MORE

4. An operator theoretic approach to the Riemann Hypothesis
University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/MatematikcentrumAbstract : In 2023 an operator theoretic approach to the Prime Number Theorem was introduced by Olsen. In this thesis this approach is examined and applied to give a new, operator theoretic, proof of a different version of the Prime Number Theorem and of the Prime Number Theorem for arithmetic progressions.

5. Classical Limits in Planetary Motion and Gravitational Radiation
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : In this report, we analyze general relativistic effects on celestial bodies, including gravitational strength in different metrics, gravitational radiation, and frame-dragging. We present simulation methods for classical and general relativistic motion, through the use of systems of equations that may be numerically integrated. READ MORE
