Millimeter Wave Localization: Slow Light and Enhanced Absorption
, 2007 We exploit millimeter wave technology to measure the reflection and transmission response of random dielectric media. Our samples are easily constructed from random stacks of identical, sub-wavelength quartz and Teflon wafers.

Characteristic Mode Analysis of Complex Spoof Localized Surface Plasmon Resonators
IEEE Access, 2018 In this paper, characteristic mode analysis (CMA) is originally applied to investigate complex spoof localized surface plasmon (LSP) resonators, including a traditional toroid spoof-LSP resonator, and three Fabry-Perot type spoof-LSP resonators with ...

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...
