TL;DR: An up-to-date literature overview on relevant approaches for controlling circuital characteristics and radiation properties of dielectric resonator antennas (DRAs) is presented in this paper.

TL;DR: In this paper, a comparative analysis of various reconfigurable and multiband antenna concepts is presented, which can be classified into three basic approaches: tunable/switchable antenna integration with radio-frequency switching devices, wideband or multiband antennas integration with tunable filters, and array architectures with the same aperture utilized for different operational modes.

TL;DR: The propagation of Pulsed Electric Fields in a stratified media stack made up by stratum corneum, epidermis, dermis, and fat has been carefully modeled and results clearly highlight that new research efforts are needed to ensure the considered communications due to the severe impairment suffered by electromagnetic waves.

TL;DR: In this article, a hybrid modeling approach based on geometrical and physical optics is adopted in order to efficiently analyse the multiple wave reflections occurring within the lens and to evaluate the relevant impact on the radiation properties of the antenna under analysis.

TL;DR: In this article, an accurate finite-difference time-domain (FDTD) scheme for modeling timedomain wave propagation in arbitrary dispersive biological media is proposed, which is based on the direct solution of the timedomain Maxwell equations by using the Riemann-Liouville operator for fractional differentiation.
