Spectrum occupancy measurements and lessons learned in the context of cognitive radio (2016)
Presentation / Conference Contribution
Mehdawi, M., Riley, N. G., Ammar, M., Fanan, A., & Zolfaghari, M. (2015, November). Spectrum occupancy measurements and lessons learned in the context of cognitive radio. Presented at 2015 23rd Telecommunications Forum, TELFOR 2015

Various measurement campaigns have shown that numerous spectrum bands are vacant even though licenses have been issued by the regulatory agencies. Dynamic spectrum access (DSA) based on Cognitive Radio (CR) has been regarded as a prospective solution...

Quality measurements of an UWB reduced-size CPW-fed aperture antenna (2016)
Book Chapter
Zolfaghari, M., Riley, N. G., Mehdawi, M., Fanan, A., Ammar, M., & Meng, F. (2016). Quality measurements of an UWB reduced-size CPW-fed aperture antenna. . Institute of Electrical and Electronics Engineers. https://doi.org/10.1109/TELFOR.2015.7377526

The paper presents a characterization of a compact co-planar waveguide (CPW)-fed slot loaded low return loss planar printed antenna designed for wireless communication and ultra-wideband (UWB) applications. Following a review of the antenna design, w... Read More about Quality measurements of an UWB reduced-size CPW-fed aperture antenna.

Comparison of spectrum occupancy measurements using software defined radio RTL-SDR with a conventional spectrum analyzer approach (2016)
Presentation / Conference Contribution
Fanan, A., Riley, N., Mehdawi, M., Ammar, M., & Zolfaghari, M. (2016, November). Comparison of spectrum occupancy measurements using software defined radio RTL-SDR with a conventional spectrum analyzer approach. Presented at 2015 23rd Telecommunications Forum Telfor (TELFOR)

In the present day Cognitive Radio has become a realistic option for solution of the spectrum scarcity problem in wireless communication. Recently, the TV band has attracted attention due to the considerable potential for exploitation of available TV...

Multi-scale characterisation of the 3D microstructure of a thermally-shocked bulk metallic glass matrix composite (2016)
Journal Article
Zhang, W., Bodey, A. J., Sui, T., Kockelmann, W., Rau, C., Korsunsky, A. M., & Mi, J. (2016). Multi-scale characterisation of the 3D microstructure of a thermally-shocked bulk metallic glass matrix composite. Scientific reports, 6(1), 18545-1-18545-7. https://doi.org/10.1038/srep18545

Bulk metallic glass matrix composites (BMGMCs) are a new class of metal alloys which have significantly increased ductility and impact toughness, resulting from the ductile crystalline phases distributed uniformly within the amorphous matrix. However... Read More about Multi-scale characterisation of the 3D microstructure of a thermally-shocked bulk metallic glass matrix composite.
