Broadband Butler Matrices with the Use of High-Pass LC Sections as Left-Handed Transmission Lines

An application of left-handed transmission line sections in Butler matrices has been investigated. It has been shown, for the first time, that the utilization of both left-handed and right-handed transmission lines allows for broadband differential phase shifters’ realization, required in the Butler matrices. A complete theoretical analysis is given, for Butler matrices incorporating ideal transmission lines of both right- and left handed types and expressions for the achievable bandwidth and differential phase deviation are derived. The presented idea has been verified by the design of a 4 x 4 Butler matrix operating in a frequency range of 2.5 – 3.5 GHz. As an artificial left-handed transmission line, an equivalent high-pass LC circuit realized in a quasi-lumped element technique, has been considered, and the resulting phase shift of such a circuit is given analytically. The obtained measurement results fully confirm the validity of the proposed idea of broadband Butler matrices’ realization

Smart antenna beamforming network

Smart Antenna with RF beamforming capability can greatly improve the performance of the vehicle communication system by providing better link quality and high immunity to interference. Butler Matrix is a well-known beamforming network. It can be used for multibeam antennas. The Butler Matrix increases the system capacity and provides higher signal to interference ratio, consequently enhancing the overall system performance. Several studies have been conducted related to the cascading Butler Matrix. In an Multi Port Amplifier (MPA) application, a signal entering one port of the Butler Matrix is divided into equal parts. The signal is then amplified by all the amplifiers and then recombined by the combining Butler Matrix at the output port that corresponds to the particular input port.Suarez also reported that the introduction of the cascading Butler Matrices improves the performance of antenna parameters such as cross over and beam orthogonality

The unburiable: Representations of pain and violence in selected works of Sarah Kane and Caryl Churchill

In this thesis I intend to answer the question of how representations of pain and violence in the selected plays of Kane and Churchill assist the critical understanding of those works. The works I have selected are Sarah Kane’s Blasted and Caryl Churchill’s Seven Jewish Children: A play for Gaza. To assist the understanding of the spectator and to enable me to engage with the plays in closer detail I draw on a selection of theories from the philosophers Judith Butler and Arne Johan Vetlesen. In particular I discuss Butler’s theorisation of grief, vulnerability and responsibility to (and for) the Other. I also discuss Vetlesen’s responses to pain and torture, with emphasis on his notions of pain transference. From my reading and analysis of the plays, I find that both works provoke a complex set of responses to issues of communal responsibility and identity. The reference in the title to ‘the unburiable’ is a term coined by Butler to explain the efforts of some people to dehumanise the Other. Applying the theoretical ideas of Butler and Vetlesen to the plays provides a way to negotiate the fragile gap between those that matter and those who have become the unburiable
