1. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction
University essay from Umeå universitet/Institutionen för fysikAbstract : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

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).
