Dual-polarity metamaterial circular polarizer based on giant extrinsic chirality
Chirality is ubiquitous in nature. The associated optical activity has received much attention due to important applications in spectroscopy, analytical chemistry, crystallography and optics, however, artificial chiral optical materials are complex and difficult to fabricate, especially in the optical range. Here, we propose an ultrathin dual-polarity metamaterial circular polarizer by exploiti...
متن کاملDeflection and Free Vibration of Sandwich Panel with Honeycomb Core on Winkler Elastic Foundation
In this paper deflection and free vibration of sandwich panel is studied. The core of Sandwich panels is made of hexagonal honeycomb and faces are made of two different materials of Carbon Fiber Reinforced Plastic and K-aryl/epoxy covering. The governing equations are deduced from the First order Sheer Deformation Theory (FSDT) and they are solved using Generalized Differential Quadrature Metho...
متن کاملA Circular Split Ringdouble Negative Metamaterial Having Simultaneous Negative Permittivity and Permeability
The scope of this paper is to design and simulate a novel circular split ring structure having simultaneous negative permittivity and permeability so called double negative metamaterial or left handed material. The DNG structure consists of five circular split ring resonators on one side of dielectric medium and a couple of circular wires on other side. The complex permittivity, permeability, i...
متن کاملComparison between Metamaterial based circular patch antenna and microstrippatchAntenna
The Metamaterial based antenna is designed for some improvement in the performance of directivity gain, return loss and size of circuit area. A patch antenna has been designed and fabricated to operate between 1Ghz.-3Ghz. The aim of the project is to design and fabricate metamaterial antenna and study the effect of antenna dimensions Length (L), Width (W) and substrate parameters relative Diele...
متن کاملDouble-negative acoustic metamaterial.
We show here the existence of acoustic metamaterial, in which both the effective density and bulk modulus are simultaneously negative, in the true and strict sense of an effective medium. Our double-negative acoustic system is an acoustic analogue of Veselago's medium in electromagnetism, and shares many unique consequences, such as negative refractive index. The double negativity in acoustics ...
