The results of this letter provide a general strategy for reducing the number of multiport measurements of microwave circuits.Covering design | covering number | design of experiments (DOE) | Impedance | Impedance measurement | Microwave circuits | Microwave measurement | multiport measurement | Scattering | scattering matrix | scattering parameter | Scattering parameters | Turán number | Turán system | vector network analyzer (VNA) | Wireless communicationjournal article10.1109/LMWC.2022.32152902-s2.0-85141584111https://api.elsevier.com/content/abstract/scopus_id/85141584111
