All these technologies use electromagnetic spectrum bandwidths for which current isolators are not suitable.&nbsp;An isolator is needed to prevent reflected waves from distorting measurements or damaging other components. Thus the absence of a workable isolator represented a major limitation to the use of THz wave sources.&nbsp;<\/p>\n\n\n\n<p>Dr. Morandotti\u2019s work at INRS provides the first solution to this problem, using a strontium iron oxide (SrFe<sub>\u00ad12<\/sub>\u00adO\u00ad<sub>19<\/sub>) magnet, which has the additional benefit of requiring no external magnetic field.&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dr. Roberto Morandotti and his team at the INRS \u00c9nergie Mat\u00e9riaux T\u00e9l\u00e9communications Research Centre have developed a device that is critical to the use of terahertz (THz) sources for a variety of applications.
