Numerical and experimental generated data during project https://doi.org/10.1038/s41598-024-59512-7

The dataset was generated using a procedure that allows for independent control of all center frequencies of multi-band passive microwave circuits. To achieve this goal, an automated decision-making procedure is developed in which a set of orthogonal scaling directions are determined based on their effect on individual circuit bands, and using auxiliary optimization sub-problems. The scaling range is then automatically computed by solving an appropriately-defined least-square design relocation problem. The methodology introduced in the work is illustrated using two planar passive devices. In both cases, wide-range operating frequency re-design has been demonstrated and favorably compared to conventional gradient-based tuning.
