The ever increasing wireless data services, such as imaging, video, audio, multimedia, etc., have demands for the very high speed wireless communications and network, which are unfortunately a bottleneck when combining with the wireline core network. Users' are now expecting high quality of experience with low-cost devices, ubiquitous connectivity, energy efficiency, high reliability, or even ultra-low latency if a vehicle terminal is applied.

Inhomogeneous spatial polarization state of vectorial optical field is of importance in biophotonics, communication, single molecule imaging and optical tweezers etc[1]. It have been reported that the radial sub-wavelength nanoslits can generate vector field due to the surface plasmon polarization effect[2], but fabrication of nanoslits in gold still remains a daunting challenge. To achieve high quality orbital polarization with high extinction, the width of nanoslits should be below wavelength. Conventional fabrication method for such a structure is to employ electron beam lithography(EBL) in negative tone resist with high sensitivity. However, there is always a problem in the lift off process because of the hardness in cured negative tone resists. To overcome this difficulty, a novel EBL process in a bilayer of PMMA/NEB has been developed. The top resist NEB is used to define line-width since the developer for NEB is alkali TMAH, which doesn‘t attack PMMA, NEB lines can be independently replicated on PMMA. A subsequent dry etch in O2 plasma can etched away the PMMA layer using NEB lines as mask, after this step, a deposition of 150-nm thick gold is carried out, followed by a lift off in hot acetone. Radial nanoslits with the width of 100 nm defined by NEB line-width have been successfully fabricated by using this novel process. Optical demonstration of manipulating polarization state by radial slits is under the way. In summary, the brand new concept of EBL combine the merit of positive and negative tone resists, which makes the fabrication of the radial nanoslits become more easily.

Multi-channel media access control (MAC) is important in wireless sensor networks because it allows parallel data transmissions and resists external wireless interference. Existing multi-channel MAC protocols, however, do not efficiently support delay-sensitive applications that require reliable and timely data transmissions. In addition, multi-channel operation is inherently deficient for supporting multi-hop broadcasting, due to independent waking-up schedules on sensors. To address these issues, we present a routing-enhanced multi-channel MAC (RM-MAC) which allows nodes to coordinately select their channel polling times based on cross-layer routing information. RM-MAC also supports a ripple broadcast mechanism which achieves efficient multi-hop broadcast among sensors. Simulation results show that RM-MAC provides significant improvement over the MuCHMAC [1], in terms of end-to-end delay, under a wide range of traffic loads including both unicast and broadcast traffic.

Microwave, MTT-S International Symposium

An energy-efficient dual-band ASK transceiver for intra/inter-chip communication is proposed in this paper. The transmitter is implemented with two coupled VCOs which have two modes and generate two carrier frequencies (75 GHz/85 GHz) with low power consumption. Meanwhile, the receiver consists of a wideband LNA, an envelope detector and output buffer. The LNA has a peak gain of 27 dB at 86 GHz, a bandwidth of 28 GHz from 65 GHz to 93 GHz and a power consumption of 7 mW. Intra-chip communication channels are implemented by on-chip transmission lines. Prototype ASK transceiver is fabricated in TSMC 65 nm CMOS process with an area of 0.42 mm 2 . A spectrum and transient measurements show the bandwidth achieves up to 8 GHz with a power consumption of 13 mW.

Power Line communication (PLC) is a communication technology that uses the existing distribution power grids for data transmission. Because of the high attenuation in the power line channel, transmission between two distant nodes must be done through relay technology. What's more, since strong noise exists in power grids the packet error rate may be high even when two nodes are close. This paper proposes a distributed relay scheme based on network coding that is designed for this high packet loss environment. Simulation results show that the proposed approach performs better than a fixed-path relay scheme in which only an end-to-end acknowledgement is enabled.
