Efficient parameter representation for broadband REMS models

Determine whether broadband analyses of reconfigurable electromagnetic structures using the proposed circuit-theoretic and far-field interaction framework require storing model parameters individually for all frequencies of interest, or whether more memory- and compute-efficient representations can be developed.

Background

The modeling method is formulated for narrowband analysis but can be generalized to broadband by treating each frequency separately.

Such a generalization may require significant storage and computation if parameters must be kept for all frequencies.

The authors explicitly identify as open whether per-frequency storage is necessary or if more efficient representations exist, highlighting a key scalability concern for broadband REMS modeling.
