1. 1. Establishing High-Temperature Models for Leakage Current in Gated Lateral Bipolar Junction Transistors

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Jimmy Atterstig; [2024]
   Keywords : Electronics; leakage current; brokaw bandgap; semiconductor physics; gauss-newton;

   Abstract : Power-efficient circuits are a vital step in moving towards a greener future. Battery life can get substantially improved by decreasing the amount of power a circuit needs. Lower power also leads to less excess heat generated. READ MORE

3. 2. Modelling and Optimisation of Relativistic Magnetron with Transparent Cathode : Applications for High-Power Microwaves

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : David Sawert; [2023]
   Keywords : Relativistic Magnetron; RM; High-Power Microwaves; HPM; Particle-in-Cell; PIC; MAGIC3D; TE11;

   Abstract : This thesis aimed to investigate the relativistic magnetron (RM), which is a high-power microwave (HPM) source. Since the RM can generate high-intensity microwave radiation, it can be used as a pulsed electromagnetic weapon to target electronic systems in different objects, such as drones, missiles, or vehicles.

4. 3. Particle Simulation and Optimization of a Relativistic Magnetron for HPM Applications

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Wilhelm Thunberg; [2022]
   Keywords : Relativistic Magnetron; FOI Magnetron; TE11; HPM; High Power Microwaves; Particle in cell; MAgic3d;

   Abstract : A relativistic magnetron (RM) is a high-power microwave (HPM) source. The main objective of the RM is to generate directed electromagnetic pulses with high power, which can be used in e.g. HPM weapons and for electromagnetic compatibility testing. READ MORE

5. 4. Towards Underwater UV Communication- Simulation and Experimentation on Penetration of UV Radiation into Sea water.

   University essay from Blekinge Tekniska Högskola

   Author : Subhash Chandra Ranga; [2021]
   Keywords : Optical Communication; Underwater communication Underwater communication Optical communication; Underwater communication Acoustic communication; Underwater communication Microwave communication; Visible Light Communication; Refractive Index.;

   Abstract : People around the globe are immensely trying to connect using light as carrier due to its low power consumption and high data transfer rates. Sound and microwaves are examples of other carriers that can be used, although they aren't nearly as efficient as light. A method of communicating is using light beneath the surface of the water.

6. 5. Theoretical analysis and simulation of microwave-generation from a coaxial vircator

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Martin Hägg; [2017]
   Keywords : HPM; high power microwaves; vircator; virtual cathode oscillator; cst; particle-in-cell; PIC; particle studio; microwave weapon; HPM; high power microwaves; virtual cathode oscillator; HPM; mikrovågor; strålvapen; CST; particle in cell; BAE systems; virkator; strålkälla; högeffekts mikrovågor; koaxiell virkator;

   Abstract : High-power microwave, HPM, systems can be used as non-lethal weapons with the ability to destroy or disturb electronics, by damaging internal circuits and inducing high currents. Today microwave sources are being developed with peak powers exceeding 1 GW, one of these devices is the vircator, a narrowband source which is unique to the HPM community. READ MORE
