$$\bar{\varvec{S}}$$ Matrix from a Two-Dimensional Slab Covered by Water Drops in W and J Bands: Comparison of a Full-Wave Method with Measurements
This paper presents a full-wave method, based on the method of moments (MoM), to calculate the \(\bar{\varvec{S}}\) matrix from a two-dimensional complex sample in millimeter and submillimeter W and J bands. From the surface currents obtained by inverting the impedance matrix and from the Huygens principle, the reflection and transmission coefficients are computed. This allows us to obtain the four elements of the \(\bar{\varvec{S}}\) matrix. Firstly, the method is validated from canonical samples (a dielectric slab and a stack of two dielectric slabs) by applying the well-known Fresnel coefficients. Secondly, for the W (75 to 110 GHz) and J (220 to 330 GHz) bands, a PVC slab covered by water drops is considered, for which the \(\bar{\varvec{S}}\) matrix is compared with measurements made in quasi-optical free space. A satisfactory agreement is obtained between the measurements and the model.
期刊介绍:
The Journal of Infrared, Millimeter, and Terahertz Waves offers a peer-reviewed platform for the rapid dissemination of original, high-quality research in the frequency window from 30 GHz to 30 THz. The topics covered include: sources, detectors, and other devices; systems, spectroscopy, sensing, interaction between electromagnetic waves and matter, applications, metrology, and communications.
Purely numerical work, especially with commercial software packages, will be published only in very exceptional cases. The same applies to manuscripts describing only algorithms (e.g. pattern recognition algorithms).
Manuscripts submitted to the Journal should discuss a significant advancement to the field of infrared, millimeter, and terahertz waves.
