These accelerating charges will in-turn perturb the free-spac e electromagnetic fields to which they are coupled\, causing radiation of electromagnetic waves. However\, this picture implies that antennas must n ecessarily be made primarily of conductive metal and\, although this is su itable for the microwave range\, where metals are close to ideal conductor s\, Ohmic loss unfortunately increases with respect to frequency. To compe nsate for this\, growing interest in reaching higher frequencies has spurr ed the fundamental re-imagination of antenna design\, this time with a die lectric focus. As a result\, a working understanding of the wireless syste ms of the present and future will demand a firm grasp of the core principl es of dielectric radiators. This talk will provide an overview spanning fr om classical microwave-range works\, through the mm-wave antennas that low -temperature cofired ceramics have made possible\, to contemporary cutting -edge all-dielectric radiators for terahertz and light-waves\, which are e tched photolithographically from high-purity semiconductors.\n\nSpeaker’ s bio:\n\nDr. Daniel Headland earned his Ph.D. in Electrical and Electroni c Engineering from The University of Adelaide\, Australia\, in 2017.
