1. Dielectric properties of ion-exchanged electrotechnical insulation papers : A study on the properties of novel papers
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Electrical insulation papers are a widely used group of papers in insulation applications and has been used for more than 100 years. Common applications include use as the dielectric medium in capacitors and insulation material in cables, bushings and transformers. LÄS MER
2. Numerical Simulations of Wave Propagation between a Left-Handed Material and a Right-Handed Material
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The discovery of metamaterials has led to major advances in different fields of physics including optics, microwave engineering and acoustics. Specific to theoretical electromagnetism, the introduction of metamaterials have led to the development of negative-index materials (NIMs) with simultaneous negative permittivity and negative permeability with backward-wave propagation.

3. Undersökning av materialegenskapers inverkan på mikrovågsuppvärmningen av grafit
Kandidat-uppsats, Uppsala universitet/Fasta tillståndets elektronikSammanfattning : Mikrovågsuppvärmning är en viktig process som används i många industriella tillämpningar. Användningen av mikrovågsuppvärmning inom industri är dock inte lika utbredd som den har potential till att vara på grund av orsaker som säkerhet, strålning och brist på kunskap. LÄS MER
4. Measurement of the Complex Permittivity of Phantoms for 5G/6G Compliance Tests
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In late 2019, 5G, the next generation of networktechnology was first deployed. The first deployment covers onlya small part of the total data transfer needs. In order to increasedata transfer, the frequency band used, must be increasedtowards the millimeter wave.As the frequency band is increased, safety studies must be done. LÄS MER
5. Simulation of FMCW mode MIMO Radar for Performance Analysis as Industrial Safety System
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In industrial environments workers can be prone to dangerous situations that may cause harm. In order to prevent accidents and fulfill legislative requirements for safe working condition, a safety system can be needed to be installed in place. LÄS MER
