A novel smart antenna is described, which is conceived as a low complexity inexpensive upgrade for IEEE 802.11b/g Wireless Local Area Network (WLAN) systems. Using smart antennas to increase network throughput by improved spatial reuse is not normall

In radio networks, cell sizes are determined by the power needed to provide an acceptable signal-to-noise ratio to a certain percentage of a given coverage zone. Propagation within buildings introduces losses to the system. If the losses can be minim

BACKGROUND The aim of this study was to determine whether the efficacy of the combination of 5-fluorouracil (5-FU), leucovorin (LV) and radiation therapy (RT) could be improved by the addition of interferon-alpha2b (IFN-alpha) in patients who have ha

This paper examines the practical application of advanced theoretical techniques, based on a hybrid combination of circuit theory and rigorous electromagnetic field solutions, to two distinct, but fundamentally related, problems. The first concerns a

Passive metamaterials suffer from narrow bandwidths and high losses due to limits imposed by causality. Actively loaded metamaterials on the other hand may be designed to overcome these limitations, with the caveat that stability may be difficult to
