In this paper, a novel design of broadband monopole optical nano-antennas is proposed. It consists of a corrugated halfelliptical patch inside an elliptical aperture. Full-wave electromagnetic simulations have been used to investigate the performance of the nano-antenna. The predicted performance of the proposed monopole nano-antenna is remarkably broadband. Moreover, the proposed broadband nano-antenna can respond to light waves with different polarizations. The proposed optical antenna will pave the way towards the development of high performance optical antennas and optical systems.
Plasma polymerization of fluorocarbon was processed through dielectric barrier discharge (DBD). A thin hydrophobic
film packed with nano-particulate structure was obtained on cotton fabric surface. The contact angle of the water and 1-bromonaphthalene on coated cotton fabric was 133° and 124° separately. The surface morphology of the coating was
observed through SEM (Scanning Electronic Microscope). It was found that cotton fabric surface was tightly adhered to
a thin film packed by nano-particles from 10nm to 200nm. This process showed potential applications in continuous
coating of textiles with functional nano-particulate polymers, but without changing their softness performance.
PTFE nano-crystallines with different morphology and crystal structures were rapidly formed by an Atmospheric Plasma
Polymerization at room temperature without any catalysts or templates. Transmission electron microscopy (TEM) and
X-ray diffraction (XRD) results indicated single crystal phase of the nano-crystallines. Other characterization methods,
such as Polarization optical micrographs of the nanocrystallines at high temperatures showed their higher thermal
stability compared to the PTFE bulk polymers. The atmospheric oriented plasma polymerization can serve as a common
method for nanofabrication of many other single crystalline polymer systems.
