Optimization of an electret-based energy harvester
, 2011 Thanks to miniaturisation, it is today possible to imagine self-powered systems that use vibrations to produce their own electrical energy. Many energy-harvesting systems already exist. Some of them are based on the use of electrets: electrically charged

Large Transverse Thermoelectric Effect in Weyl Semimetal TaIrTe4 Engineered for Photodetection
Advanced Functional Materials, EarlyView.This experimental work shows that the anomalous scanning photocurrent response patterns of the Weyl semimetal TaIrTe4${\rm TaIrTe}_4$ under visible and long‐wave infrared illumination are due to a large transverse thermoelectric response of the material.

Ultra directive antenna via transformation optics
, 2009 Spatial coordinate transformation is used as a reliable tool to control electromagnetic fields. In this paper, we derive the permeability and permittivity tensors of a metamaterial able to transform an isotropically radiating source into a compact ...

Fluid Forces Control Structural Remodeling of Blind‐Ended Lymphatic Microvessels
Advanced Healthcare Materials, EarlyView.Using innovative microfluidic biofabrication with fluid mechanical insights, we recapitulated the blind‐ended microanatomy and physiological drainage properties of capillary lymphatics. Our results reveal the interrelationship between intra‐ and extraluminal regions of lymphatic vessels due to flow‐induced sprouting and morphological changes that ...

Finite Element Analysis of Electromagnetic Waves in Two-Dimensional Transformed Bianisotropic Media
, 2015 We analyse wave propagation in two-dimensional bianisotropic media with the Finite Element Method (FEM). We start from the Maxwell-Tellegen's equations in bianisotropic media, and derive some system of coupled Partial Difference Equations (PDEs) for ...

Application of COMSOL Multiphysics for Nanosphere Dimer
DEStech Transactions on Computer Science and Engineering, 2018 A simple nanosphere dimer system was constructed based on the wave optics module in COMSOL Multiphysics to verify their hot spots effect. By mapping their electric field distributions, we found that as the nanogap decreases or the nanosphere radius increases in a way, the field enhancement of the dimer goes up. In addition, the resonant peak along with
