Description

This item was taken from the IEEE Conference ' Modelling of experimental set-up for material studies based on a periodic lattice with a defect operating in the 215 GHz to 230 GHz frequency range ' One-dimensional (1D) periodic structures with a localized defect and operating in the mm and sub-mm wavelength ranges can be formed by machining small perturbations on the waveguide's walls. We demonstrate the applicability of such structures for diverse applications: from particle acceleration to materials research. It is shown that the strong field enhancement inside the sizable lattice defect should allow material analysis in strong electric fields, as well as construction of novel particle accelerating structures and klystron cavities. The design of the apparatus to launch the radiation is also discussed.
