“…According to a literature survey, propagation modelling in layered structures can be carried out according to some, different methodologies, spanning Sommerfeld integration methods [7], multipath formulations through the Green's functions representation [8], full numerical solutions [16] andmost of all -models based on either the Dyadic Green Function (DGF) [17]- [21] or Geometrical optics (Ray Tracing -RT) [2], [5], [14], [15], [22]. DGF is a physics based approach to propagation modelling aiming at the asymptotic evaluation of the overall received field, whereas RT addresses the different field contributions propagating along different optical paths that can be tracked between the transmitting and the receiving locations.…”

Nowadays, many wireless applications require the exchange of electromagnetic waves through propagation environments that look like to stratified media to some extent. This may concern both natural scenarios, e.g., air/vegetation/ground, and artificial structures, like meta-materials, photonic devices, solar cells or systems-on-chip. The characterization of the layered propagation channel is therefore important for the design and deployment of effective devices and systems. To this aim, the Dyadic Green Function method has been often leveraged, although its use is usually limited to simple sources, like short dipoles or current elements. Furthermore, it seems unsuited to assess the dispersive properties of the channel, which are known to become important when high data-rate must be conveyed. In this paper, a ray-based approach to propagation inside layers is proposed. As the layered environment can be quite reverberating, a great number of rays may be needed, to the extent that the corresponding computational burden might be hardly afforded by general purpose ray tracing tools. Therefore, the ray tracing engine here presented is specifically conceived for the layered case, and mostly relies on analytical formulation. The accuracy of the model is checked against measurement carried out at chip scale at optical frequency, as a reference study case.INDEX TERMS Electromagnetic propagation, layered media, ray tracing, system-on-chip, wireless communications.FRANCO FUSCHINI received the M.Sc. degree in telecommunication engineering and the Ph.D. degree in electronics and computer science from the University of Bologna in March 1999 and in July 2003, respectively, where he is currently an Associate Professor with the Department of Electrical, Electronic and Information Engineering "G.

“…The electromagnetic reaction concept [57,79] can be employed to simplify the formulation and the resolution of boundary-value problems. In our formulation, reaction integrals have appeared in (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19). The quantity E is,m , H js,n is the the reaction between E is,m and H js,n , and this can be understood as a physical measurable capacity of coupling between such fields.…”

“…The analysis of a multilayered media is a topic of interest of many recent researches [2][3][4][5][6][7][8][9] that investigate artificially engineered materials. Scattering and propagating electromagnetic models are popular in many applications such as: nondestructive testing [10,11], structural monitoring of components [12], design and evaluation of well-logging sensors in the oil and gas industry [13][14][15][16] underwater electromagnetic communication [17], among others.…”
