Implantable drug delivery system: Frontiers of medicine‐engineering interdisciplinary

Interdisciplinary Medicine, EarlyView.
This review systematically summarizes the driving mechanisms of implantable on‐demand drug delivery systems (IDDS), including endogenous, exogenous, and closed‐loop strategies. It highlights the pivotal roles of flexible electronics and miniaturization in enhancing the tissue conformity and spatial adaptability.

Horn Image-Guide Leaky-Wave Antenna

IEEE Transactions on Microwave Theory and Techniques, 1981
A novel approach for designing a frequency-scanning millimeter-wave antenna is described. The antenna is constructed by using an image wide leaky-wave antenna embedded in a long trough with metal flares along both sides. The optimum flare angle for achieving maximum gain is theoretically predicted.

Leaky-wave antennas

2016
Millimeter waveguides, such as coplanar lines, microstrip lines and dielectric guides, are open structures where energy leakage is bound to occur. This leakage can occur, for example, when there are discontinuities in the guiding structure, or perhaps when the guide is excited in an inappropriate mode.

Leaky-Wave Antennas

Proceedings of the IEEE, 2012
This paper gives a basic review and a summary of recent developments for leaky-wave antennas (LWAs). An LWA uses a guiding structure that supports wave propagation along the length of the structure, with the wave radiating or “leaking” continuously along the structure. Such antennas may be uniform, quasi-uniform, or periodic.
