Journal ArticleDOI
Misalignment Sensitivity of Strongly Coupled Wireless Power Transfer Systems
TL;DR: In this article, the authors proposed a novel set of strongly coupled magnetic resonance (SCMR)-based topologies that are less sensitive to misalignment while providing large wireless powering efficiencies.
Journal ArticleDOI
An Origami Reconfigurable Axial-Mode Bifilar Helical Antenna
TL;DR: In this paper, a new reconfigurable origami bifilar helical antenna is presented, which can change its operating frequencies by changing its height, and analytical equations for the design of such antennas are derived based on an equivalent model of a standard helical antennas.
Journal ArticleDOI
Electromagnetic Wave Propagation into Fresh Water
TL;DR: In this article, the transmission loss and propagation loss of RF waves penetrating into fresh water are calculated for various propagation depths for air-to-water communications from air to fresh water.
Journal ArticleDOI
Wireless Power Transfer in Concrete via Strongly Coupled Magnetic Resonance
TL;DR: In this paper, the authors studied the wireless efficiency of the strongly coupled magnetic resonance (SCMR) method for non-homogenous interfaces for wireless power transfer from a source in air to a sensor embedded in concrete and modeled the concrete material properties for various humidity levels using the extended Debye model.
Journal ArticleDOI
HIRF penetration through apertures: FDTD versus measurements
TL;DR: In this paper, the FDTD method is used to predict the shielding effectiveness of conducting enclosures with apertures, and the numerical results are compared with measurements. Several issues related to FDTD analysis of highly resonant and high-quality factor (high-Q) structures, such as windowing and acceleration techniques, are examined and discussed.
