Epsilon-Near-Zero (ENZ) Metamaterials and Electromagnetic Sources: Tailoring the Radiation Phase Pattern
In this work, we investigate the response of epsilon-near-zero (ENZ) metamaterials and plasmonic materials to electromagnetic source excitation. The use of these media for tailoring the phase of radiation pattern of arbitrary sources is proposed and analyzed numerically and analytically for some canonical geometries. In particular, the possibility of employing planar layers, cylindrical shells ...
متن کاملExperimental characterization of optical nonlocality in metal-dielectric multilayer metamaterials
The optical nonlocality in metal-dielectric multilayer metamaterials is characterized experimentally as a function of the angle of incidence with respect to the TE-polarized incident light. The physical mechanism of the difference between the nonlocal effective permittivity and the effective-medium-theory-based effective permittivity depending on the incident angle is theoretically revealed thr...
متن کاملLensing system and Fourier transformation using epsilon-near-zero metamaterials
Metamaterials and metastructures with effective relative permittivity near zero exhibit unusual wave properties such as uniform phase distributions across such domains. Here we discuss the possibility of using εnear-zero (ENZ) metamaterials for lensing and Fourier transforming. Owing to the possibility of having ENZ metamaterials in different wavelength regimes, the concepts shown here can be u...
متن کاملDirectional and monochromatic thermal emitter from epsilon-near-zero conditions in semiconductor hyperbolic metamaterials
The development of novel thermal sources that control the emission spectrum and the angular emission pattern is of fundamental importance. In this paper, we investigate the thermal emission properties of semiconductor hyperbolic metamaterials (SHMs). Our structure does not require the use of any periodic corrugation to provide monochromatic and directional emission properties. We show that thes...
متن کاملMicrowave Sensor Using Metamaterials
It is well known that electromagnetic wave can be applied to wireless communication, radar, heating and power transmission. It has brought human society into industrial and information age. The mechanism behind these applications is electromagnetic radiation, i.e. energy transportation and conversion. Recently, research shows that evanescent wave, which is non-radiation wave associated with gui...
