Intruguing non-linear phenomena discovered at JMU!

How is it possible that a voltage signal excited by infrared radiation decays as the excitation source remains on?  Anita Vincent-Johnson, who graduated in physics at JMU on May 2012, found that the strange phenomenon might be due to chaotic transport in a thermoelectric power generator interacting with infrared radiation.  The mystery is not fully unveiled and the team of Dr. Scarel continues the investigations.  The latest news were published today:
