Modeling of Large Microwave Cavities for Industrial and Scientific Applications
The cavities of microwave heating devices need to be carefully designed in order to ensure safe, efficient operation and homogeneous field distributions. The size, the number of modes and the resonant nature of a cavity can pose difficulties for their simulation. This paper discusses the modeling of microwave cavities and demonstrates how a system for heating test samples was optimized using electromagnetic simulation.

Coaxial / Rectangular Converter for the High-Power Microwave Applications
Broad-band (2GHz-6GHz) converter was simulated with CST MICROWAVE STUDIO®, and the measurements are currently carried out. The coverter is able to transfer TEM-mode of the coaxial line to the TE10-mode of the rectangular waveguide, and is suitable for...
A Unit Cell Model of a Single Periodic Waveguide Phased-Array Antenna
A single periodic open-ended waveguide phased-array antenna is analysed with a dielectric radome of variable thickness at its aperture. As a verification it is shown that the superposition of two independent plane waves shows the same field pattern as...
Advanced Modeling and Measurement of Wideband Horn Antennas
This paper presents the excellent correlation of measurement results to the numerical calculations of a SATIMO dual-ridge horn antenna which include the directivity, boresight gain, and return loss vs. frequency.
Analysis of a High Efficiency Reflector Feed Array
This article demonstrates the application of CST MICROWAVE STUDIO® (CST MWS) to the analysis of large reflector feed arrays. An array consisting of 19 elements was simulated but a larger array of more than 100 elements may also be simulated since the...
Bandpass Waveguide Filter with Dual Mode Cavities
This waveguide filter has been simulated with CST MICROWAVE STUDIO® general purpose frequency domain solver applying a tetrahedral mesh. This particular design is a waveguide bandpass iris filter for standard X-band military satellite communications.
