چکیده

The purpose of this research is to present efficient models of novel materials and surfaces based on metamaterials (MTM) and/or electromagnetic band-gap structures (EBG) suitable for large scale simulation in electromagnetic compatibility (EMC) problems. It is shown that the employment of digital filter (DF) techniques provides an efficient means of describing such materials (which inevitably consist of several electrically small components) in a large scale coarse mesh suitable for modelling practical EMC problems. The basic structure of the DF and its embedding into a TLM solver are briefly described together with the derivation of the DF parameters for the EBG and MTM materials.

Dual-band, Dynamically Tunable Plasmonic Metamaterial Absorbers Based on Graphene for Terahertz Frequencies

In this paper, a compact plasmonic metamaterial absorber for terahertz frequencies is proposed and simulated. The absorber is based on metamaterial graphene structures, and benefits from dynamically controllable properties of graphene. Through patterning graphene layers, plasmonic resonances are tailored to provide a dual band as well as an improved bandwidth absorption. Unit cell of the design...

Dynamic behaviour of concrete containing aggregate resonant frequency

The need to design blast resistant civilian structures has arisen due to aggressor attacks on many civilian structures around the world. Achieving vibration and wave attenuation with locally resonant metamaterials has attracted a great deal of consideration due to their frequency dependent negative effective mass density. In this paper, metaconcrete, a new material with exceptional properties i...

A New Circular Polarization Metamaterial Ferrite Phase Shifter

In this paper, a new X band Metamaterial (MTM) based ferrite phase shifter is presented. The phase shifter is excited by circular polarized wave base on combination of TE10 and TE01 modes in a square waveguide. In order to synthesize negative refractive index metamaterial (NIM), negative permeability of ferrite slabs in extraordinary mode is mixed with the negative permitivity of printed period...
