A tunable liquid antenna is designed and analyzed. The ability of adjustment is realized with the help of a thin post penetrating the solid dielectric and the liquid layers. The influence of the thickness and parameters of the substrate is investigated. The performance of different liquid materials including sea water, oil and distilled water is analyzed as well. The influence of the distribution...
A core-shell structure based on three-dimensional micro-cuboids connected by photonic nanojets is proposed with the aim for power enhancement of surface plasmon polaritons. The performance of the core-shell micro-cuboid is evaluated and compared with the dielectric micro-cuboid. The dependence of the power enhancement with the metallic shell is also evaluated and demonstrated that the metallic shell...
We present the first photonic nanojet analysis in the non-spherical micro-particles. The electric intensity distributions in the vicinity inside and outside a non-spherical micro-particle have investigated by using the finite-difference time-domain calculation. The non-spherical micro-particle is truncated by the cutting thickness. The shape dependence of the photonic nanojet has been investigated...
A dynamic response of liquid microlens using dielectric force was demonstrated using comparison between experimental and simulation results. The theoretical results of the simulation match fairly well with the experiment in liquid microlens with a diameter of 500 μm. An high speed motion camera with a speed of 3000 fps was used to capture the images of dynamic response for 500μm, 2mm and 5mm droplets...
The actuation of micro liquid droplets using dielectric force was demonstrated on a patterned concentric electrode by experiments and simulation. The strength of electric field around the contact line was maximum when the voltage applied. When the voltage changed from 0 V to 200 V, the contact angle of the droplet varied from 90deg to 126deg for the electrode with a diameter of 500 mum and varied...
