Infrared optical response of LuFe2O4under dc electric field

Determination of electric-field, magnetic-field, and electric-current distributions of infrared optical antennas: a near-field optical vector network analyzer.

In addition to the electric field E(r), the associated magnetic field H(r) and current density J(r) characterize any electromagnetic device, providing insight into antenna coupling and mutual impedance. We demonstrate the optical analogue of the radio frequency vector network analyzer implemented in interferometric homodyne scattering-type scanning near-field optical microscopy for obtaining E(...

Rhythmic motion of a droplet under a dc electric field.

The effect of a stationary electric field on a water droplet with a diameter of several tens micrometers in oil was examined. Such a droplet exhibits repetitive translational motion between the electrodes in a spontaneous manner. The state diagram of this oscillatory motion was deduced; at 0-20 V the droplet is fixed at the surface of the electrode, at 20-70 V the droplet exhibits small-amplitu...

Response of A Saline Solution Containing A Macromolecule To An External Electric Field

The dynamical behavior of a model for body fluids in response to an external electric field is computationally investigated for communication frequencies. The effect of an applied potential difference between two electrodes in a saline solution containing a rodlike macromolecule is studied by solving the Poisson and ion continuity equations simultaneously using the finite element method (FEM). ...

Measurement of Electric Near Field Distribution by Optical Electric Field probe

Recently through technique development of communication and information devices, the frequency used has come to extend into the gigahertz range. Especially, smaller probes of broadband with high-resolution are requested in the EMC field to measure and analyze devices. An optical electric field probe may present an accurate method for near-field measurement in the gigahertz range. In the present...
