“…Multi-modal sources, called Scale-Changing Sources, are artificially incorporated at all scale levels for the derivation of the network. When the complex surface presents both large regions and fine details -but no structures at intermediary scale levels-, mono-modal sources are able to model the electromagnetic coupling between the disparate scale levels [3][4][5]. However, for objects involving multiple structures whose size covers a large range of scale, monomodal sources fail to provide accurate numerical results while the ScaleChanging Sources allow the modelling of the scale crossing from the smallest to the highest scale (the number of modes in these sources can be derived from numerical convergence criteria).…”

Abstract-The concept of Scale-Changing Network is reported for the electromagnetic modeling of complex planar structures composed of a collection of metallic patterns printed on a dielectric surface and whose size covers a large range of scale. Examples of such multi-scale structures are provided by multi-band frequency-selective surfaces, finite-size arrays of non-identical cells and fractal planar objects. Scale-Changing Networks model the electromagnetic coupling between various scale levels in the studied structure and are computed separately. The cascade of Scale-Changing Networks bridges the gap between the smallest and the highest scale levels and allows forming a monolithic (unique) electromagnetic formulation for the global electromagnetic simulation of complex planar structures. Derivation of these networks is presented and key advantages of the electromagnetic approach are reported.

“…Although such unintended coupling between components plays an important rule in the circuit performance, this quantity is very complex to evaluate. In the recent years, several techniques in bringing this forward into the circuit design space has been investigated [2][3][4][5][6][7]. Mainly based on the resolution of Maxwell's equations to quantify the EM field in a structure, these numerical methods generated advanced fullwave EM simulation tools [8,9] that have demonstrated their efficiency in terms of accuracy, but still require huge computation time and memory space.…”

Because of ever-higher operating frequencies and circuit integration, electromagnetic (EM) coupling effects are becoming increasingly important in microwave integrated circuits. Existing EM-based numerical methods can generate accurate models for passives but suffer from high computation time and memory requirements, while fast table look-up models and equivalent circuit models do not adequately include distributed EM coupling between adjacent components. Using simple network theory principles and de-embedding concepts, the proposed technique allows fast and efficient computation of such coupling, making the design more reliable.
