1. 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.

2. Electromagnetic Phase Engineering With Metamaterials
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Metamaterials are artificially designed materials with desired electromagneticresponses for advanced wave manipulation. Their key constituent is often somenoble metal, thanks to its well localized plasmonic effects with highextinction cross section. LÄS MER
3. 3D Printing a Maxwell Fish Eye Lens With Periodic Structures
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : With the rise of high frequency communication systems such as 5G, new types of antennas has to be developed in order to meet the new requirements. In recent years, lens antennas made of periodic structures has been shown to have desirable performance when increasing operational frequency without increasing the size of the antennas. LÄS MER
4. Towards a tunable nanometer thick flat lens
Magister-uppsats, Uppsala universitet/MaterialfysikSammanfattning : This report examines the cross sections of silver microresonators subjected to an incident light with different polarization. The microresonators had different geometries with and without broken symmetries. LÄS MER
5. Study of Two-dimensional Kirigami in Different Materials
Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : De mekaniska egenskaperna hos ett tvådimensionellt material kan ändras med hjälp av Kirigami, som är en japansk klippkonst i papper. Material där man med geometriförändringar ändrar materialegenskaperna kallas metamaterial. LÄS MER
