Optical Pulling Force in Carbon Nanotubes: Manifestation of Nonlocal Conductivity
Tomer Berghaus, Touvia Miloh, Gregory Ya. Slepyan
We develop a new theory of an optical force exerted on a carbon nanotube (CNT) with a nonlocal conductivity. The optical force is expressed in terms of the surface current density…
Electrodynamics of carbon nanotubes with non-local surface conductivity
Tomer Berghaus, Touvia Miloh, Oded Gottlieb +1
A new framework that can be utilized for the electrodynamics of carbon nanotubes (CNTs) with non-local surface conductivity (spatial dispersion) is presented. The model of non-loca…
Expanding Active Matter to the Third Dimension: Exploring Short and Long-Range Particle-Wall Interactions
Sandeep Ramteke, Jordan Dehmel, Touvia Miloh +2
Most active colloid experiments are quasi-2D. Here a 3D density-matched solution of active particles propelled and aligned with an AC electric field uniquely facilitates measuremen…
Hybrid Magnetically and Electrically Powered Metallo-Dielectric Janus Microrobots: Enhanced Motion Control and Operation Beyond Planar Limits
Ido Rachbuch, Sinwook Park, Yuval Katz +2
This study introduces the integration of hybrid magnetic and electric actuation mechanisms to achieve advanced motion capabilities for Janus particle (JP) microrobots. We demonstra…
Programmable Motion of Optically Gated Electrically Powered Engineered Microswimmer Robots
Matan Zehavi, Ido Rachbuch, Sinwook Park +3
Here, we report on a new class active particles capable of dynamically programmable motion powered by electricity. We have implemented physical principles that separate the propuls…
Theory of Edge Effects and Conductance for Applications in Graphene-based Nanoantennas
Tomer Berghaus, Touvia Miloh, Oded Gottlieb +1
In this paper, we develop a theory of edge effects in graphene for its applications to nanoantennas in the terahertz, infrared, and visible frequency ranges. Its characteristic fea…
Electro-Orientation and Electro-Rotation of Metallodielectric Janus Particles
Daniel Sofer, Gilad Yossifon, Touvia Miloh
The electro-rotation (EROT) and electro-orientation (EOR) behavior of metallodielectric (MD) spherical Janus particles (JP) are studied analytically and verified experimentally. Th…
Optically Modulated Propulsion of Electric Field Powered Photoconducting Janus Particles

Herein we demonstrate the ability to optically tune the mobility of electrically powered Janus particles (JP) that are half coated with various Zinc Oxide (ZnO) semiconducting laye…
Mobile Microelectrodes: Towards active spatio-temporal control of the electric field and selective cargo assembly
Alicia M Boymelgreen, Tov Balli, Touvia Miloh +1
With an eye towards next-generation, smart, micro/nanofluidic devices, capable of responding to external stimuli or changes in environment, we demonstrate a means to achieve dynami…
Spinning Janus doublets driven in uniform AC electric fields
Alicia Boymelgreen, Gilad Yossifon, Sinwook Park +1
We provide an experimental proof-of-concept for a robust, continuously rotating microstructure - consisting of two metallodielectric (gold-polystyrene)Janus particles rigidly attac…
