Controlling Metamaterial Transparency with Superchiral Fields

The advent of metamaterials has heralded a period of unprecedented control of light. The optical responses of metamaterials are determined by the properties of constituent nanostructures. The current design philosophy for tailoring metamaterial functionality is to use geometry to control the nearfield coupling of the elements of the nanostructures. A drawback of this geometry-focused strategy i...

Ultrasensitive detection and characterization of biomolecules using superchiral fields.

The spectroscopic analysis of large biomolecules is important in applications such as biomedical diagnostics and pathogen detection, and spectroscopic techniques can detect such molecules at the nanogram level or lower. However, spectroscopic techniques have not been able to probe the structure of large biomolecules with similar levels of sensitivity. Here, we show that superchiral electromagne...

A new floating sensor array to detect electric near fields of beating heart preparations.

A new flexible sensor for in vitro experiments was developed to measure the surface potential, Phi, and its gradient, E (electric near field), at given sites of the heart. During depolarisation, E describes a vector loop from which direction and magnitude of local conduction velocity theta can be computed. Four recording silver electrodes (14 microm x 14 microm) separated by 50 microm, conducti...

Near Fields of Microstrip Antennas

The paper presents an iterative method for the computation of the near fields of single layer microstrip patch antennas. A judicious combination of the advantages of the MPIE (mixed potential integral equation) method, the FFT algorithm and the biconjugate gradient leads to an efficient numerical solution. The scheme can deal with patches of arbitrary shapes and is capable of dealing with a ver...

Optical near-fields & nearfield optics

Optical methods provide exceedingly powerful tools in science and technology for measuring, analyzing and manipulating, from optical microscopy and spectroscopy to the characterization of ultrafast processes by femtosecond pulses and the modification of materials by intense laser radiation. However, when it comes to applications in the nanometer-regime, the conventional optical techniques suffe...
