  1. 1. On the Influence of Scattering From a Power-pole on an Airport Radar

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ao Hu; [2019]
    Nyckelord :Power-pole; VOR System; Airplane; EFIE; MOM; RWG; Scattering.; Kraftstolpar; VOR Systemet; flygplan; EFIE; MoM; RWG; Spridning;

    Sammanfattning : Power-poles are one of the common massive conducting structures in cities and countryside. To fulfill the remarkable increased electric power demand nowadays, the number and the size of power-poles are also growing over the past few decades. LÄS MER

  3. 2. Lower bounds on the Q-factor for small oversampled superdirective arrays over a ground plane

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Masahiro Wakasa; [2016]
    Nyckelord :;

    Sammanfattning : Base station antennas for next generation mobile communication networks will be required to have a wide bandwidth for compatibility and support multi-beam applications. Antenna arrays are one possible candidate for a next generation base station antenna since they can obtain high directivity, support multi-beam and wide angle scanning. LÄS MER

  4. 3. Efficient analysis of 2D antenna arraysusing the ASM-MBF method

    Master-uppsats, KTH/Elektroteknisk teori och konstruktion

    Författare :Sergio Amaya Maldonado; [2011]
    Nyckelord :;

    Sammanfattning : The analysis of large-scaled 2D finite planar arrays with the Method of Momentsrelying on the RWG basis functions requires a huge amount of memory for saving theequation system and a long computation time for solving the surface current distribu-tion. In this project, the Array Scanning Method - Macro Basis Function (ASM-MBF)method created by Craeye is implemented in an existing MoM’s code in order to verifythe reduction of the equation system keeping a good accuracy.

  5. 4. Implementation of a manycast protocol for intermittently connected mobile ad hoc networks in disaster areas

    Master-uppsats, RTSLAB - Laboratoriet för realtidssystem

    Författare :Ekhiotz Jon Vergara Alonso; [2010]
    Nyckelord :IC-MANET; Symbian; Random-Walk Gossip; disaster area;

    Sammanfattning : Nowadays, the use of mobile phones and other wireless devices has become an indispensable part of daily life. However, the focus of wireless communication is on infrastructure-based networks, making them prone to service outage if for any reason the infrastructure is overloaded or there is no network coverage.

  7. 5. Implementation of a Manycast Protocol in a Partitionable Mobile Ad hoc Network

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för datavetenskap

    Författare :Gustav Nykvist; [2009]
    Nyckelord :mobile ad hoc network; multi-hop; partition tolerance; random-walk gossip-based manycast;

    Sammanfattning : Wireless communication has grown very popular, and communication is the key to success in many situations. However, most of the common technologies today rely on infrastructure and in disaster situations infrastructure might be lost or get severely overloaded. This master thesis concerns intermittently connected mobile ad hoc networks. LÄS MER
