Electromagnetic (EM) skyrmions are an EM analogue of the skyrmions in condensed matter physics, offering new degrees of freedom to structure light and manipulate light–matter interactions and thus promising various groundbreaking applications in optics and photonics. Recently, there is a growing interest in composing EM skyrmions based on different field vectors of EM waves. Here, an EM skyrmion is...
Vortex modes carrying Orbital Angular Momentum (OAM) provide an ideal platform for realizing many novel physical effects and applications ranging from classical to quantum regimes. An important approach to generating the vortex modes is the electromagnetic (EM) scattering by scatterers holding high degrees of symmetries. Within this context, a clear link is established between the symmetries and the...
The design of a compact, wideband flexible monopole antenna printed on a flexible Kapton polyimide substrate is presented. The proposed antenna consists of two rhombic elements embedded within a square plane as the radiating element. The wide bandwidth is aimed at alleviating potential performance degradations due to its application in an on‐body environment. The proposed antenna is designed using...
