In this paper, we propose the design of high sensitivity and selectivity metamaterial-based biosensors operating in the THz regime. The proposed sensors consist of planar array of resonant metallic structures, whose frequency response is modified thr...

Double CSRR for water content detection in biological matter (2011)
Presentation / Conference Contribution
La Spada, L., Bilotti, F., & Vegni, L. (2011, September). Double CSRR for water content detection in biological matter. Presented at 4th EOS Topical Meeting on Optical Microsystems (OµS’11), Capri, Italy

In this study, a low-cost, compact, and high-performing metamaterial-based biosensor operating in the THz frequency range is presented. The sensor is designed to detect the presence of water content in biological matter by spectral absorption measure... Read More about Double CSRR for water content detection in biological matter.

Metamaterial resonator arrays for organic and inorganic compound sensing (2011)
Presentation / Conference Contribution

Metamaterial-based design of biological sensors operating at THz frequencies (2011)
Presentation / Conference Contribution
La Spada, L., Bilotti, F., & Vegni, L. (2011, October). Metamaterial-based design of biological sensors operating at THz frequencies

In this contribution, we present an omega-shaped electromagnetic resonator, which is of potential interest for THz biosensors. A new analytical model for such an inclusion-type is developed, considering the effects of the fringing capacitance. After...

Exploring the effects of stress history on the drained and undrained cyclic behaviour of granular materials. (2011)
Presentation / Conference Contribution
Barreto, D. (2011, January). Exploring the effects of stress history on the drained and undrained cyclic behaviour of granular materials. Paper presented at 5th International Conference on Geotechnical Earthquake Engineering (5-ICEGE)

This paper presents the results of 3D DEM simulations of granular materials subject to cyclic loading. While both the drained and undrained conditions are considered, the effects of depositional history and consolidation stress history on the stress-...

Numerical Simulation of Drain Performance in Liquefiable Soils (2011)
Presentation / Conference Contribution
Bouckovalas, G., Dimitriadi, V., Tsiapas, Y., & Tsioulou, A. (2011, January). Numerical Simulation of Drain Performance in Liquefiable Soils. Paper presented at 5th International Conference on Earthquake Geotechnical Engineering, Santiago, Chile

Modern approaches for the design of drains for liquefaction mitigation are based on the work of Seed and Booker (1977) for infinitely permeable drains and uniform soil with purely horizontal drainage. More recently, Bouckovalas et al. (2009) revisite... Read More about Numerical Simulation of Drain Performance in Liquefiable Soils.

Settlement-The Short and the Long of it (2011)
Presentation / Conference Contribution
McDougall, J. (2008, March). Settlement-The Short and the Long of it. Presented at International Symposium on Waste Mechanics

Total settlement in municipal solid waste (MSW) landfills can be considerable, from 25% to 50% of original fill thickness (Bjarngard and Edgers, 1990). Some occurs very quickly, i.e. during the filling phase (or short term), but there remains a signi... Read More about Settlement-The Short and the Long of it.
