    The importance of using a 3D model in magnetron simulation has been demonstrated using the example of an L-band, high-power magnetron simulated using the SOS/MAGIC3D program. The proper way of applying the DC voltage and the importance of end hats has been emphasised. Also the important V-I transient characteristic of the magnetron can only be obtained using a 3D model.

    AEA Technology has for many years used computer simulation for prediction and interpretation of the interaction of electromagnetic waves with charged particle flow. This paper focuses on one application area where computer modelling has been particularly successful in devising novel designs; namely, in the design of new variants of the high powered microwave tube known as the magnetically insulate...

  • The modelling of relativistic magnetrons

    Publication Year: 1997, Page(s):3/1 - 3/4

    This paper concerns a family of relativistic magnetrons with rising-sun SWS developed by Physics International (PI). The family (with the exception of one dimension of one magnetron) is geometrically self-similar. The representative member has five-fold geometric symmetry, with energy being extracted via waveguides centred on two non-adjacent shaped cavities. Unfortunately, the PI magnetron perfor...

  • Electromagnetic susceptibility analysis of slotted screens using the Generalised Circuital Analysis

    Publication Year: 1997, Page(s):4/1 - 4/3

    The shielding properties of slotted envelopes has been evaluated using the Generalised Circuital Analysis (GCA). The Finite Element Method (FEM) has been used to characterise the different circuital elements, thus yielding a very systematic and versatile approach. View full abstract»

    A commercial electromagnetic analysis code, which is based on the finite difference time domain technique (FDTD), has been parallelised as part of PEPSE, a collaborative project which was supported by the European Union under the Framework III programme. As part of the associated dissemination project (PEPSE/D), MIRA has undertaken an evaluation of this code for EMC applications. This evaluation w... View full abstract»

    In response to concern over electromagnetic compatibility (EMC) aspects of all types of electrical equipment, numerical techniques for field computation are becomingly increasingly important in the struggle to meet the required EMC standards. This paper describes a programme of work undertaken to assess the suitability of electromagnetic finite element analysis for modelling power electronic circu... View full abstract»

    Daresbury Laboratory currently operates a 2 GeV electron synchrotron radiation source (SRS), used by many academic and industrial concerns into the research of materials, structures and interfaces. As part of the development of synchrotron radiation research in the UK, a feasibility study has been initiated to replace the now elderly SRS with a world leading radiation source which would enable sus...

  • Application of Superfish for modelling cavity and dielectric structures

    Publication Year: 1997, Page(s):8/1 - 8/6
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (354 KB)

    Superfish is a finite difference package written to solve the TM and TE resonant frequencies and field distributions in an RF cavity with two dimensional cartesian or three dimensional cylindrical symmetry. In this paper it is applied to the modelling of cavity resonators, and dielectric resonators enclosed in conductive housings. View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (241 KB)

    This paper presents a finite element method for calculating resonant frequencies for a arbitrary three dimensional cavities. Firstly traditional nodal methods are considered and the reason for their failure in modelling high frequency fields. An edge element formulation and its solution of the problems of spurious modes and modelling of re-entrant corners is presented. With the aid of realistic ca... View full abstract»
