You might need to be careful with the negative resistance side - you only need one more storage element and a bit of non-linearity (both of which you could get from the power device driving the coil) and you&#39;d have Chua&#39;s circuit, wouldn&#39;t you (the Lord of Chaos will be stomping around) - but it would be a fun thing to experiment with.</p><img src="https://community.element14.com/aggbug?PostID=3252&AppID=13&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/technologies/test-and-measurement/b/blog/posts/quantum-mechanical-concept-used-to-improve-the-range-of-wireless-chargingFri, 30 Jun 2017 12:49:54 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:015e08fe-1258-4192-aa61-3c164ebf0f2dmichaelkellett0<p>Fake (or massively overhyped) news !!</p><p>&nbsp;</p><p>Cabe, please, filter this stuff at least&nbsp; a little bit.
