Query: 2D Simulation of High-Efficiency Cross-Field RF Power Sources   An efficient method for frequency domain analysis of 2D cross-field devices
is presented. This work was done to analyze and design high efficiency
magnetrons. Arbitrary device-geometries are described by a piecewise planar
boundary. The method is based on an expansion of the electromagnetic fields
into a set of cavity eigenmodes. In order to obtain the self-consistent
solution, iterations are performed until the energy balance is reached. A
boundary integration method is used to take into account space charge effects.
The cavity eigenmodes are found by a method based on the scattering matrix
technique. The geometry is divided into regions. The boundary contour
mode-matching method is used to obtain the scattering matrices for each region.
Electromagnetic fields in each region are expanded into a series of plane
waves. Due to choice of plane wave expansion, all integration in the
mode-matching process is carried out analytically. The scattering matrices of
the regions are combined using a generalized scattering matrix technique to
obtain the scattering matrix for the full geometry, and then the eigenmode
resonance frequencies and the fields. Periodic boundary condition is used for
the field calculation and the particle tracking.
