Abstract:
In this work, a full-wave partial element equivalent
circuit (PEEC) model for 2-D periodic metallic structures is
proposed. The mixed potential integral equations (MPIEs) with
periodic Green’s function (GF) are interpreted as loop equations
following Kirchhoff’s voltage law (KVL) in a circuit domain.
The impact of gauge freedom in the MPIE on the corresponding
PEEC model is discussed. A tailored gauge function is introduced
to form a generalized PEEC model for periodic structures, which
demonstrates superior passivity and frequency stability. With
the proposed PEEC model, lumped and active elements can
be easily integrated with conducting bodies for field-circuit cosimulation.
Through the distributed circuit including coupling
elements, the PEEC model provides a clear physical insight
into the electromagnetic behavior of the physical models for
design and optimization. Three numerical examples, including
frequency-selective surface (FSS), array antenna, and pixelwise
meta-atom, are given to illustrate the accuracy and efficiency of
the proposed PEEC model.
