Updating high-resolution MRI

How can you make a high-frequency MRI machine more precise? By taking an electrical engineering approach to creating a better, uniform magnetic field.

Beyond good vibrations: New insights into metamaterial magic

If invisibility cloaks and other gee-whiz apps are ever to move from science fiction to science fact, we'll need to know more about how these weird metamaterials actually work. Michigan Tech researcher Elena Semouchkina has ...
