Krishna spent a significant part of his career on inter-disciplinary research that enabled novel electromagnetic (EM) applications of electronic materials such as conductive polymers (CPs), radiofrequency
(RF) magnetic thin-films and carbon nanomaterials. He made seminal contributions to microwave characterization of CPs such as poly(aniline) and PBT, and showed that these materials possess EM wave
absorption and shielding effectiveness superior to metal impregnated composites.
He developed accurate numerical methods to extract the microwave constitutive parameters (conductivity, permittivity etc.) from broadband measurements and formulated theoretical EM models to demonstrate new applications of CPs,
such as microwave absorbers with adaptive conductivity for frequency-selective interference suppression.
His current research utilizes nanomaterials such as CNTs and graphene for enhancing the tunability and bandwidth of planar antennas, and is also advancing nanotechnology-based wireless sensors to detect
environmental contaminants (such as ammonia and ozone). His publications on the characterization of novel EM materials, EM scattering, parametric estimation methods, antenna design, sensors and computational
EM have been cited in over 1250 journal articles and 12 patents. In recognition of his innovative research over several years, Krishna has been nominated in Feb 2016 to the IEEE Fellow Grade with the citation “For
interdisciplinary contributions to novel electromagnetic materials and parametric estimation methods for electromagnetics problems.
