Apparently the same scientist published the description of these materials 10 years ago in Nature:<p><a href="https:&#x2F;&#x2F;www.researchgate.net&#x2F;profile&#x2F;Kosmas_Tsakmakidis2&#x2F;publication&#x2F;5843358_Nature_Trapped_Rainbow_Storage_of_Light_in_Metamaterials&#x2F;links&#x2F;541054f70cf2df04e75d2438&#x2F;Nature-Trapped-Rainbow-Storage-of-Light-in-Metamaterials.pdf" rel="nofollow">https:&#x2F;&#x2F;www.researchgate.net&#x2F;profile&#x2F;Kosmas_Tsakmakidis2&#x2F;pub...</a>

Ho. Lee. Shit. I&#x27;m in the satellite telecoms domain - this is incredible and will have far reaching consequences after a decade. Unfortunate that R&amp;D and hardware lead times are so long in this industry.

<i>&quot;For more than 100 hundred years, these systems were held back by a limitation that was considered to be fundamental ... But that limitation is now a thing of the past.&quot;</i><p>We should bear breakthroughs like this in mind every time someone appeals to fundamental limitations of physics (or any other field).<p>So many times I hear people object that something can&#x27;t be done because of some fundamental limit. But research like this proves that limits that are considered fundamental sometimes aren&#x27;t, and we can&#x27;t know ahead of time which of these limits really are fundamental and which only appear so.

Doesn&#x27;t the time-bandwidth reciprocity fall out of the same math as the Heisenberg Uncertainty Principle? Does this work have implications for HUP &quot;workarounds&quot;?

&gt; &quot;Other potential applications include ... broadband light harvesting and energy storage, and broadband optical camouflaging (&quot;invisibility cloaking&quot;).&quot;<p>Obviously these sorts of announcements often have hype in them - and that&#x27;s fine - but could someone really invent a cloaking device with this advancement?

Very interesting - reminds me of superconductors. Some quantity which normally cannot be escaped (ie, everything has some amount of resistance, or the Q factor is a finite number) that under certain special conditions can actually hit its singularity. Special conditions which necessitate exotic new theory.<p>Also, call me cynical but it seems like the natural application is pulsed laser weapons. Now instead of spending infinity dollars on a portable megawatt laser that can gimbal to attack a target, you have a kilowatt laser that charges a waveguide until it has equivalent energy to the megawatt laser and then discharges it as necessary.

&gt; &quot;The reported breakthrough is completely fundamental —we&#x27;re giving researchers a new tool. And the number of applications is limited only by one&#x27;s imagination,&quot; sums up Tsakmakidis.<p>I like the idea of having a new tool available, but don&#x27;t know why everything has to be sooo revolutionary and unlimited.
