摘要：
To mitigate the two limitations existing in the conventional procedures of Nicolson-Ross-Weir (NRW) method, namely thickness resonance and multi-value problems, an alternating iteration algorithm is proposed for accurately retrieving the complex permittivity of non-magnetic materials based on rectangular waveguide measurements. The mechanism for the generating of the two limitations are reviewed and explained with the detailed procedures. Then, two different types of formulas are combined together for alternately iterative calculation, effectively eliminating two limitations simultaneously. The proposed algorithm has been described, and verified with numerous simulations as well as experiments, exhibiting robustness and high accuracy.
