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(...
متن کاملMeasurement 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...
متن کاملNear-field focusing with optical phase antennas.
We investigate the near-field focusing properties of three-dimensional phase antennas consisting of concentric rings designed to have source and image spots separated by several microns from the lens. Tight focal spots are obtained for silicon or gold rings patterned in a silica matrix. We analyze in detail the dependence of the performance of these lenses on geometrical parameters such as the ...
متن کاملFrom near-field optics to optical antennas
July 2011 Physics Today 47 In a prophetic letter to Albert Einstein on 22 April 1928, Irish scientist Edward Hutchinson Synge proposed a microscopic imaging method in which an optical field scattered from a tiny gold particle could be used as a radically new light source. The gold particle, Synge argued, would act as a local probe of some sample of interest, with the scattered light transmitted...
متن کاملEvaluation of E-field distributions in parallel transmit systems by time-domain optical electric-field sensors
Introduction and Motivation Ensuring RF safety is crucial for parallel transmission in MRI. In general, during parallel transmission the E-field distributions inside and outside the body exhibit a complex time evolution which cannot be covered by calorimetric SAR measurements. Furthermore, the knowledge of E-field evolution at selected positions would afford a better understanding of the compli...
