“…Recently, Zou used lateral wave in a four-layered model for interlayer debonding detection in asphalt airport pavement [18]. The problem addressed in this paper parallels the analysis carried out in published work on the EM field of the horizontal electric dipole (HED) [19]. The actual formulas are, of course, quite different.…”

Electric dipoles are the fundamental components of a planar multi-layered circuit. Present work focuses on the theoretical investigations of radiation field due to a vertical electric dipole in a four-layered region composed of a perfect conductor covered with two dielectrics and the air above. Locating a vertical electric dipole (VED) on or near the air-dielectric boundary, approximate formulas are obtained. The resultant analytical formulas have the merit of offering unique insights about the characteristics of the radiation field including direct waves, reflect waves, lateral waves, and trapped surface waves. The amplitude of the field along the boundary exhibits the dependence of ρ −1/2 , which is an intrinsic characteristic of trapped surface waves, where ρ is the propagation distance. In addition, the radiation field is further examined for propagation distance and propagation characteristics of the interference phenomenon. Furthermore, when the observation angle Θ ≥ 88 • , the lateral wave still exists; however, the trapped surface wave is a major component of the total field. The proposed formulas have potential to develop planar four-layered circuit structures.

In this paper, the influence of the earth resistivity characteristics on the radiant field excited by a very low frequency(VLF) horizontal wire antenna is studied, and a 1D isotropic model of the horizontal layered earth is established. Theoretical formulas for the apparent resistivities of the layered ground and the electromagnetic field of antennas are derived for the case of observation points being on both of the site of antennas and far areas. The effects of different earth resistivity and multilayered earth on the radiation performances of the VLF horizontal antenna are simulated and analyzed. From the derivations and analyses, it is pointed out that the VLF horizontal antennas built on a region of high resistivity is conducive to radiant electromagnetic field effectively.

When power is to be transferred to a mm-sized \gls{imd}, located multiple cm deep inside the human body, the main goal is often to maximize the received power, within the applicable \gls{sar} limits. It has been shown that, for equivalent homogeneous biological tissue, there is little difference between the received power using \gls{wpt} at (sub-)GHz frequencies compared to low MHz frequencies. However, it remains unclear whether the introduction of additional tissue layers, thus more accurately approximating the real environment, changes the optimal frequency for maximum received power. This paper presents an analytical model that can be used to calculate the \gls{em} fields, \gls{sar}, received power, and \gls{pte} in a planarly layered environment, consisting of an arbitrary number of layers with arbitrary thicknesses and arbitrary dielectric properties. The model is first validated by comparing it to CST Studio Suite\textregistered. It is then used to determine the optimal frequency for \gls{wpt} to a mm-sized implant, located multiple cm deep inside the human body. The optimal frequency is 10 kHz, and the received power is approximately constant up to 300 kHz. The same holds for the \gls{pte}.
