On the Alignment of Low-Fidelity and High-Fidelity Simulation Spaces for the Design of Microwave Waveguide Filters. IEEE Transactions on Microwave Theory and Techniques. 66(12):5183-5196. https://doi.Abstract-The objective of this paper is to advance the stateof-the-art of Aggressive Space Mapping (ASM) by demonstrating how, for resonant structures, and microwave filters in particular, an ASM based optimization procedure may converge to the desired target performance in just one step. This behavior is first justified in physical terms, using the Electromagnetic (EM) cavity perturbation theory, and is then investigated numerically. Several practical filter design demonstrations are also presented. The paper is concluded with a conceptual definition of Space Alignment in the context of ASM.
The objective of this paper is to use Electromagnetic based Computer-Aided Design tools to investigate the maximum tuning range of channel filters, typically used in satellite payloads. Both circular and rectangular waveguide technologies are investigated. The results of the investigation show that single-mode rectangular waveguide implementations offer substantially wider tuning range, as opposed to classical dual-mode circular waveguide implementations. In addition to simulations, measurements are also presented indicating very good agreement with theory, thereby fully validating the Computer-Aided Design procedure.
Space Mapping (SM) and Aggressive Space Mapping (ASM) techniques are widely used in the synthesis and design of microwave filters. Their popularity stems from the inherent simplicity of the procedures and from their effectiveness. The objective of this paper is to extend the state-of-the-art of these techniques by discussing how they can also be used very effectively to tune microwave filters. In addition to theory, the successful tuning of a six-pole inductive waveguide filter is discussed in details thereby fully validating the proposed SM techniques.
