By applying logarithmic‐exponential operation, spectral decomposition, Schur decomposition, and singular value decomposition (SVD) algorithm, the T‐parameters of electromagnetic simulated unit circuit (ESUC) can be reconstructed with arbitrary fractional exponent, therefore continuous tuning optimization is realized. By reducing optimization costs of 19%, 13%, and 15% and specification error of 18%, 33%, and 14% across verification examples, respectively, the proposed TSM not only overcomes the integer‐only tuning constraint in prior arts but also achieves the shortest optimization time and smallest specification error. Verification is also provided through comparative analyses and discussions. 10.1002/mop.70526 http://onlinelibrary.wiley.com/termsAndConditions#vor |
