Electronics Letters, 2008 A novel wideband planar dipole antenna is proposed. This antenna has a simple structure and compact size. For verification, the newly proposed structure was fabricated and measured. It is shown that the return loss of the antenna between 3.0 and 7.5 GHz is better than - 10 dB. The radiation performance is good over the whole frequency band.

Tuning the Scattering Response of the Optical Nano Antennas Using Graphene
IEEE Photonics Journal, 2014 In this paper, we propose the tuning of the optical nano antenna in the visible spectrum using graphene. A dipole structure for the nano antenna is considered with the resonating wavelength at the VIS-NIR spectrum range. Resonance is determined using the

Charge‐Induced Morphing Gels for Bioinspired Actuation
Advanced Functional Materials, EarlyView.This study introduces a novel electroactive actuation mechanism that enables the gel material to generate substantial and reversible shape‐changing while preserving topological and isochoric (volumetric) equivalence. The resultant morphing behaviors can mimic the movements of muscle‐driven organelles in nature, including cilia‐like beating and ...
