Twisted split-ring-resonator photonic metamaterial with huge optical activity.
Coupled split-ring-resonator metamaterials have previously been shown to exhibit large coupling effects, which are a prerequisite for obtaining large effective optical activity. By a suitable lateral arrangement of these building blocks, we completely eliminate linear birefringence and obtain pure optical activity and connected circular optical dichroism. Experiments around a 100 THz frequency ...
متن کاملCompact Ultra Wide Band Microstrip Bandpass Filter Based on Multiple-Mode Resonator and Modified Complementary Split Ring Resonator
A new class of broadband microstrip filters for Ultra Wide Band (UWB) applications is proposed. In the design, different stages of parallel-coupled microstrip line and other stages with a Modified Complementary Split Ring Resonator (MCSRR)-a concept proposed here for the first time-are adjusted to obtain the desired response with broadband, sharp rejection, low insertion loss, and low return lo...
متن کاملCompact Metamaterial-Based UHF RFID Antennas: Deformed Omega and Split-Ring Resonator Structures
Over the past decade, researchers have shown significant advances in the area of radio frequency identification (RFID) and metamaterials. RFID is being applied to a wide spectrum of industries and metamaterial-based antennas are beginning to perform just as well as existing larger printed antennas. This paper presents two novel metamaterial-based antennas for passive ultra-high frequency (UHF) ...
متن کاملCompact triple-band metamaterial inspired monopole antennas
Here we present a comparison analysis on the single loop resonator (SLR) inspired triple-band monopole antennas. Two configurations with rectangular and circular shaped radiation patches are presented. Simultaneously, two feed techniques with coplanar waveguide and microstrip feeds are performed to drive the antennas. And the conventional planar monopole antennas without the SLRs are also analy...
متن کاملDual-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...
