Atomistic Surrogate-Based Optimization for Simulation-Driven Design of Computationally Expensive Microwave Circuits with Compact Footprints
Abstrakt
A robust simulation-driven design methodology for computationally expensive microwave circuits with compact footprints has been presented. The general method introduced in this chapter is suitable for a wide class of N-port un-conventional microwave circuits constructed as a deviation from classic design solutions. Conventional electromagnetic (EM) simulation-driven design routines are generally prohibitive when applied to numerically demanding microwave circuits with highly miniaturized and complex topologies. The key idea of the approach proposed here lies in an iterative redesign of a conventional circuit by a sequential modification and optimization of its atomic building blocks. The speed and accuracy of the presented method has been acquired by solving a number of simple optimization problems through surrogate-based optimization (SBO) techniques. Two exemplary designs have been supplied to verify the proposed method. An abbreviated wideband quarter-wave impedance matching transformer (MT) and a miniaturized hybrid branch-line coupler (BLC) have been developed. Diminished dimensions of the constructed circuits have been achieved by means of compact microstrip resonant cells (CMRCs). In the given examples, an implicit space mapping (ISM) technique has been utilized as a SBO engine. In general, the proposed method is compatible with other SBO routines as well. The final results have been acquired in only a fraction of time that is necessary for a direct EM optimization to generate competitive results. Numerical results have been validated experimentally.
