Lens Antennas – Analysis and Synthesis at mm-waves

In this paper short introduction in dielectric lens antennas at mm-waves will be given. Dielectric lens antennas become more popular as applications start to migrate to higher frequencies where lens dimensions and weight become small enough and allow easy integration. Typically used feeds and lens shapes will be discussed together with global optimization techniques and analyzing kernels employ...

Guest editorial for the special issue

IP has become the dominant networking paradigm for the present century. The evolution towards an all-IP core network infrastructure continues, with an enriched IP layer often implementing the networking functionalities directly on top of WDM (Wave Division Multiplexed) links. Furthermore, IP over switched 1/10 GigaEthernet is replacing the traditional, relatively slow-speed, access technologies...

Guest Editorial Special Issue: Configuration

Configuration can be defined as the composition of a complex product from instances of a set of component types taking into account restrictions on the compatibility of those component types. For supporting product configuration, different AI approaches are well established as central technologies in industrial configuration systems. However, the wide industrial use of configuration technologie...

Guest editorial: special issue on electronic voting

T HIS special issue provides representative samples of the excellent research being carried out in electronic voting today—in areas as diverse as statistics, usability, cryptography, formal methods in security and experimental computer security analysis. It is perhaps the first broadly defined special issue of a technical journal in this rapidly growing and important research area. The last few...
