Fast EM-driven parameter tuning of microwave circuits with sparse sensitivity updates via principal directions
作者：
Highlights：
• Fast algorithm for microwave design with principal directions is developed.
• Sensitivity updates are restricted to directions of maximum response changes.
• Principal directions are selected through an automated decision-making process.
• Proposed approach is demonstrated to yield significant computational savings.
• Efficiency improvements do not compromise optimization process reliability.
