Pencil-Beam Single-point-fed Dirac Leaky-Wave Antenna on a Transmission-Line Grid
, 2016 Leaky-wave antennas (LWAs) are widely used as single-point-fed linear antenna arrays. The extension of LWAs to 2D implies that they can be used as single-point-fed 2D antenna arrays without requiring a complex feeding network.

Monitoring of atopic dermatitis using leaky coaxial cable [PDF]
, 2017 In our daily life, inadvertent scratching may increase the severity of skin diseases (such as atopic dermatitis, etc.). However, people rarely pay attention to this matter, so the known measurement behavior of the movement is also very little ...
