Leading national thinking on politics, government & public policy through Open Access research

Strathprints makes available scholarly Open Access content by researchers in the School of Government & Public Policy, based within the Faculty of Humanities & Social Sciences.

Research here is 1st in Scotland for research intensity and spans a wide range of domains. The Department of Politics demonstrates expertise in understanding parties, elections and public opinion, with additional emphases on political economy, institutions and international relations. This international angle is reflected in the European Policies Research Centre (EPRC) which conducts comparative research on public policy. Meanwhile, the Centre for Energy Policy provides independent expertise on energy, working across multidisciplinary groups to shape policy for a low carbon economy.

    Use of overmoded interaction structures to obtain higher powers from mm-wave vacuum electronic sources is an approach that is being used in the research reported here. To provide mode selectivity a two dimensional corrugated periodic structure is constructed on the inner surface of the conducting cylindrical slow wave interaction region that is excited by an annular electron beam. This two dimensional structure consists of a periodic surface lattice that is designed to facilitate coupling of the wave fields to generate a powerful single frequency output, even though the ratio of the diameter of the structure to the emitted wavelength is ~5. Recent measurements of the output of this mm-wave source are presented.
