Stacked optical antennas for plasmon propagation in a 5 nm-confined cavity
The sub-wavelength concentration and propagation of electromagnetic energy are two complementary aspects of plasmonics that are not necessarily co-present in a single nanosystem. Here we exploit the strong nanofocusing properties of stacked optical antennas in order to highly concentrate the electromagnetic energy into a 5 nm metal-insulator-metal (MIM) cavity and convert free radiation into gu...
متن کاملOptical Antennas
Optical antennas are an emerging concept in physical optics. Similar to radiowave and microwave antennas, their purpose is to convert the energy of free propagating radiation to localized energy, and vice versa. Optical antennas exploit the unique properties of metal nanostructures, which behave as strongly coupled plasmas at optical frequencies. The tutorial provides an account of the historic...
متن کاملResonant optical antennas.
We have fabricated nanometer-scale gold dipole antennas designed to be resonant at optical frequencies. On resonance, strong field enhancement in the antenna feed gap leads to white-light supercontinuum generation. The antenna length at resonance is considerably shorter than one-half the wavelength of the incident light. This is in contradiction to classical antenna theory but in qualitative ac...
متن کاملCircular Polarization in Stacked Hexagonal Shaped Microstrip Antennas
The various perturbing structures for generation of circular polarization (CP) in a hexagonal shaped microstrip antenna (HMSA) with patch side length of 20 mm is used to resonate in the Mobile Satellite Service (MSS) band at a centre frequency of 2 GHz. The hexagonal geometry to achieve CP is perturbed in four different ways: first with a rectangular slot at centre, second with two narrow slits...
