  1. 11. Increasing the Crossover Levels of Beams in Geodesic Luneburg Lens Antennas

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Philip Arnberg; [2021]
    Keywords : Luneburg lens; geodesic lens; generalized Luneburg lens; crossover level and lens antennas.; Luneburg lins; geodetisk lins; generaliserad Luneburg lins; korsningsnivåer och linsantenner.;

    Abstract : The new and forthcoming generation of mobile networks intend to operate at considerably higher frequencies than the previous systems. This lift in frequency of operation alleviates today’s communication systems’ crowded bandwidth and allows for faster data rates than previously possible. READ MORE

  3. 12. Markov Chain Monte Carlo (MCMC) and Bayesian Inference for Gravitational Waves

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Christine Andersson; [2021]
    Keywords : Gravitational Waves; LISA; LISA mission; Bayesian Inference; Markov Chain Monte Carlo; MCMC; Bayes’ Theorem; stochastic sampling; Metropolis Hastings; histograms; Physics and Astronomy;

    Abstract : The Laser Interferometer Space Antenna (LISA) is a space borne gravitational wave detec- tor set to launch in 2034, with the objective of detecting and studying the Gravitational Waves (GWs) of our universe. So far, ground-based detectors such as the Laser Interferometer Gravitational-Wave Observatory (LIGO) have been successful in detecting GWs, but the limitations of ground based detectors is what makes LISA so special.

  4. 13. Active- integrated aperture lens antenna

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jesus Ventas Muñoz de Lucas; [2021]
    Keywords : ;

    Abstract : Luneburg lens antennas are gaining popularity in new communication systems, as increasingly higher frequencies are being used. Broadband fully- metallic implementations of Luneburg lenses, such as Rinehart- Luneburg lenses, constitute simple, cheap and efficient beamformers. READ MORE

  5. 14. 3D-Printed Geodesic Luneburg Lens Antenna With Novel Patch Antenna Feeding

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Elin Berglund; Sandis Freimanis; [2021]
    Keywords : Luneburg lens; patch antenna; geodesic; transformation optics; 3D-printing;

    Abstract : With the roll out of new technologies and the worldbecoming more connected, there is a rising demand for higherbandwidth and new frequency bands. To meet the demand,higher frequencies are used in new communication systems.Higher frequencies come with the need for new antenna designsand one promising type of antenna is the lens antenna.
