By: Lauren Russ Upgrading MRI Readability While practical applications of bulk metamaterials are still far from being developed, research suggests that healthcare could benefit from new metamaterials applications. The paper by Ricardo Marque’s, Lukas Jelinek, Manuel J. Freire, Juan Domingo Baena and Mikhail Lapine, “Bulk Metamaterials Made of Resonant Rings,” references the potential of a metamaterials application that could improve diagnostic accuracy of Magnetic Resonance Imaging (MRI) by making reports clearer to read. The paper also makes use of a rigorous homogenization treatment of these metamaterials and discusses an exciting application of such magnetic metamaterials for enhancing the resolution of surface coils in magnetic resonance imaging. Improving Cell Phones Improving cell phone performance by reducing the size of antennas is addressed in three papers in the issue. A variety of antennas have already been engineered with metamaterials (MTMs) and metamaterials- The paper “Metamaterials- Also on the topic of phone antennas, the paper by John L. Volakis, Fellow IEEE, and Kubilay Sertel, Senior Member IEEE, “Narrowband and Wideband Metamaterial Antennas Based on Degenerate Band Edge and Magnetic Photonic Crystals”, describes electrical small antennas based on unique anisotropic metamaterial structures. While the authors present several new antenna elements of much smaller size, they explain that this was done by exploiting wave slow-down techniques afforded by emulating in-plane anisotropy using simple coupled transmission line concepts. Of importance was the utilization of these elements within an antenna array to realize much smaller conformal and thin apertures achieving remarkable band-widths as much as 10:1. Transformation Optics In “Electromagnetic Design With Transformation Optics”, the first of four optics articles presents Transformation Optics (TO) as a powerful technique for designing metamagnetic and discusses several novel electromagnetic examples. According to authors Nathan B. Kundtz and David R. Smith, Members IEEE, and John B. Pendry Fellow IEEE, TO provides a design tool that is to wave optics what ray tracing is to geometrical optics. While the media required by the transformation optical approach are often complex and possibly unrealistic, the extreme flexibility in the transforms suggests that entire new classes of devices will be feasible using the developing approaches. Michael Zedler and George V. Eleftheriades Fellow IEEE address synthesizing TO in the paper entitled “Anisotropic Transmission- “Optical Metamaterials Based on Optical Nanocircuits” The metamaterials research field is vibrant, bright and is progressing steadily and strongly into various exciting forefronts which include quantum metamaterials, superconducting metamaterials, tunable and reconfigurable metamaterials, photonic metamaterials, infra-red metamaterials, and THz metamaterials to name a few. Given less than a decade of experience with the engineering applications of MTMs, there is great hope that they will provide additional degrees of freedom for the design of many different forms of electromagnetic applications.
