[Legacy Report] GUEST LECTURE ON “META MATERIALS AND APPLICATIONS TO ANTENNA DESIGN”

#Metamaterials #Lefthanded #materials #EMI.

Recently, there has been growing interest in the study of metamaterials both theoretically and experimentally. Some of these metamaterials exhibit either negative permittivity or negative permeability. If both permittivity and permeability of such materials are negative at the same frequency, then the composite possesses an effective negative index of refraction for isotropic medium and is referred to as a lefthanded metamaterial. The name is used because the electric field, the magnetic field and the wave vector form a left-handed system. These metamaterials are typically realized artificially as composite structures that are composed of periodic metallic patterns printed on dielectric substrates.

Many properties and potential applications of metamaterials have been explained by the speaker.  He also explained that the left handed metamaterials could be used to build a perfect lens with sub-wavelength resolution and informed the audience that it is the current topic of research interest in the area of design of antennas. He concluded his talk by showing some of his research results in the design of antennas using metamaterials using HFSS and MATLAB simulations.

As a part of interaction with the audience, he answered the query of one of the participants regarding the reduction of electromagnetic interference and channel noise using the antennas built with metamaterials.

The speaker briefed about the benefits of IEEE student membership in their career like continuining education, Jobs, career development on the request of the IEEE student branch counselor, Dr.K.Murali Krishna.
