Efficient semi-analytical method for the analysis of large finite connected slot arrays

We present an efficient method for the analysis of finite connected slot arrays in the presence of stratified media. The formulation is based on a spectral method of moments, where only one basis function is considered for each array element and one for each slot edge. An expression for the mutual impedance is derived in terms of a double...

Design of Wideband Wide-Scanning Dual-Polarized Phased Array Covering Simultaneously Both the Ku- and the Ka-Satcom Bands

We present the unit cell design of a wideband wide-scanning phased array operating in both Ku- and Ka-bands, for satellite communication applications. The radiating elements are dual-polarized connected slots loaded with an artificial dielectric superstrate, acting as a wide angle impedance matching (WAIM) structure. The design of the multi...

Analysis and design of connected slot arrays with artificial dielectrics

Connected arrays of slots loaded with artificial dielectric layers have been proposed to realize wideband phased arrays with large scan capability. The role of the artificial dielectric superstrate is to provide a wide angle impedance matching transformation from the impedance at the feeding port of the unit cell to the free space impedance....

Coördinatie van maatregelen: De stand van zaken

Er zijn vele manieren denkbaar waarop invulling kan worden gegeven aan de gecoördineerde inzet van verkeersmanagementmaatregelen in een netwerk. In eerste instantie wordt meestal voor een pragmatische, reactieve en op redeneerregels gebaseerde, aanpak gekozen. Daarna wordt stap voor stap naar een steeds geavanceerdere, proactieve en...

The future of traffic management: State of the art, current trends and perspectives for the future

In the world of traffic management a lot is happening and developments move quickly. Traffic Quest helps to keep track of these developments by systematically collecting, developing and transferring knowledge. The partners in TrafficQuest together cover the entire spectrum including the fundamental, theoretical knowledge about traffic management...

Multi-Agent Look-Ahead Traffic-Adaptive Control

The objective of this thesis is to create a distributed, multi-agent, approach to traffic control. This PhD thesis' focus is on the control of a network instrumented by traffic signals.A thorough literature study has been performed, reviewing the current state of the art in traffic signal control. On the basis of this literature survey, a...
