Micro rectennas: Brownian ratchets for thermal-energy harvesting (2014)
Journal Article
Pan, Y., Powell, C., Song, A., & Balocco, C. (2014). Micro rectennas: Brownian ratchets for thermal-energy harvesting. Applied Physics Letters, 105(25), Article 253901. https://doi.org/10.1063/1.4905089

We experimentally demonstrated the operation of a rectenna for harvesting thermal (blackbody) radiation and converting it into dc electric power. The device integrates an ultrafast rectifier, the self-switching nanodiode, with a wideband log-periodic... Read More about Micro rectennas: Brownian ratchets for thermal-energy harvesting.

THz Imaging with Broadband Thermal Sources (2014)
Presentation / Conference Contribution
Balocco, C., Pan, Y., Kasjoo, S., Alimi, Y., Zhang, L., & Song, A. (2014, September). THz Imaging with Broadband Thermal Sources. Presented at 39th Int. Conf. on Infrared, Millimeter, and THz Waves, Tucson, AZ, USA

We developed a THz imaging system based on a broadband thermal source (at 500°C) and an asymmetric semiconductor nanochannel, the self-switching nanodiode (SSD), as a room-temperature detector. The maximum resolution was better than 0.5 mm full width... Read More about THz Imaging with Broadband Thermal Sources.

Rectennas for Thermal-Energy Conversion (2014)
Presentation / Conference Contribution
Pan, Y., Powell, C., & Balocco, C. (2014, September). Rectennas for Thermal-Energy Conversion. Presented at 39th International Conference on Infrared, Millimeter, and THz Waves, Tucson, AZ, USA

We demonstrated the conversion of thermal energy in the form of far- and mid-infrared using a micro rectenna, consisting of a spiral antenna coupled to an ultra-fast nanodiode, the so-called self-switching device (SSD). A maximum efficiency of 0.02 %... Read More about Rectennas for Thermal-Energy Conversion.

Fault Tolerant Quadded Logic Cell Structure with Built-in Adaptive Time Redundancy (2014)
Journal Article

This paper describes research carried out using a quadded logic cell (QLC) structure with the purpose of creating a fault tolerant strategy for stuck-at faults. In order to create the tolerant built-in behaviour, the basic logic elements must have re... Read More about Fault Tolerant Quadded Logic Cell Structure with Built-in Adaptive Time Redundancy.

Self-healing Fuel Pump Controller Mapped into Memory Based Finite State Machine (2014)

We consider transceiver design for a MIMO multicast channel for simultaneous wireless information and power transfer. We assume that common information is intended for a subset of users, called information decoders (IDs), and the other users, called...

Subset Glauber Dynamics on Graphs, Hypergraphs and Matroids of Bounded Tree-Width (2014)
Journal Article
Bordewich, M., & Kang, R. (2014). Subset Glauber Dynamics on Graphs, Hypergraphs and Matroids of Bounded Tree-Width. Electronic Journal of Combinatorics, 21(4), Article 19

Motivated by the `subgraphs world' view of the ferromagnetic Ising model, we analyse the mixing times of Glauber dynamics based on subset expansion expressions for classes of graph, hypergraph and matroid polynomials. With a canonical paths argument,... Read More about Subset Glauber Dynamics on Graphs, Hypergraphs and Matroids of Bounded Tree-Width.

Interference alignment (IA) is a promising technique for interference management in wireless networks. However, the sum rate may fall short of the theoretical maximum especially at low signal-to-noise ratio (SNR) levels since IA mainly concentrates o...
