Near-Field Microwave Microscopy of Materials Properties [PDF]
Microwave Superconductivity, edited by H. Weinstock and M.
Nisenoff, (Kluwer, Amsterdam, 2001), pp. 239-269, 2000 Near-field microwave microscopy has created the opportunity for a new class of electrodynamics experiments of materials. Freed from the constraints of traditional microwave optics, experiments can be carried out at high spatial resolution over a broad frequency range.

WDM–TDM NG-PON Power Budget Extension by Utilizing SOA in the Remote Node
IEEE Photonics Journal, 2014 Today, even in access networks, data traffic is enormously increasing, a trend that causes existing passive optical network (PON) infrastructures to become bottlenecks in a tele- and data-communication infrastructure, which is aimed to be both broadband ...

Reconfigurable Three‐Dimensional Superconducting Nanoarchitectures
Advanced Functional Materials, EarlyView.3D superconducting nanostructures offer new possibilities for emergent physical phenomena. However, fabricating complex geometries remains challenging. Here 3D nanoprinting of complex 3D superconducting nanoarchitectures is established. As well as propagating superconducting vortices in 3D, anisotropic superconducting properties with geometric ...

Advanced Healthcare Materials, EarlyView.A magnetic microrobot fabricated by Spirulina platensis is proposed to accumulate in tumor regions and generate in situ high calcium concentration and sufficient oxygen. These characteristics of the microrobot present a strategy for triggering calcium overload therapy and chlorophyll‐mediated photodynamic therapy, and such combination resulted in a ...

Microwave-to-optical frequency conversion based on the Lamb shift [PDF]
arXiv, 2018 We consider the microwave-to-optical frequency conversion based on the Lamb shift, fine structure and forbidden transitions. The theory of such a conversion is developed and the efficiency of the microwave-to-optical frequency conversion is calculated. We show that the ratio of the peak power of the induced optical emission to the power of the incident

Gain enhancement wideband CPW antenna based on artificial magnetic conductor
Scientific ReportsUnidirectional radiation and, hence, gain enhancement can be achieved by placing a primary radiator (simple antenna) at suitable height over a reflector to diminish back radiation and to enhance the forward radiation.

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose
Advanced Materials, EarlyView.Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

Reconfigurable On-chip Photoconductive Switches [PDF]
arXiv, 2019 Microwave photonics uses light to carry and process microwave signals over a photonic link. However, light can instead be used as a stimulus to microwave devices that directly control microwave signals. Such optically controlled amplitude and phase-shift switches are investigated for use in reconfigurable microwave systems, but they suffer from large ...
