N2 - Orbital angular momentum (OAM) wave distinguish itself from non-vortex wave (NVW) with their helical phase front. As a result, the Poynting vector of such helical phase front also exhibits a helical form, which rotates around the axis that beam propagates, rather than being parallel to it. Hence, compared to NVW, the penetration and loss characteristics of OAM wave in lossy dielectric medium, such as human tissue, could vary from that of NVW. In this paper, we simulate and analyze the power penetration depth (PPD) of OAM vortex wave (VW) and NVW impinging upon skin tissue. Similarity and difference are discussed by comparing the PPD between VW and NVW, for cases with tissue presented in the near and far fields of the source, respectively.
