Using a plasmonic graphene ring resonator of resonant frequency 10.38 THz coupled to waveguide, we design lab-on-a-chip optophoresis system that can function as an efficient force switch. Finite difference time domain numerical simulations reveal appropriate choice chemical potentials the waveguide and keeps proposed structure in on-resonance condition, enabling selectively trap nanoparticle. Moreover, change 250 meV potential (i.e., equivalent 2.029 V corresponding applied bias) switches...
Given the sub-wavelength trapping challenges in optical tweezers, plasmonic tweezers serve as a bridge by breaking diffraction limit. Hence, development of can open up many potential applications biology, medicine, and chemistry. In this paper, using localized surface plasmons (LSPs) graphene nanodisk with resonance frequency 20 THz, we design lab-on-a-chip optophoresis system, which be utilized to effectively trap nanoparticles. The LSPs generate large field gradient deep area around...
There are many methods for fabricating electron linear accelerator cavities. In the present research two were chosen: first, separable parts (separate ring and disks) second, parallel disks cylinder (integrated). The resonance frequencies of cavities quality factor each frequency important parameters in their performance. comparison measured made with methods, firstly by network analyzer machine secondly using HFSS simulator. results both practical measurements simulation structures...
