1. A system comprising:
a heater having a first heating element and a second heating element, the first heating element configured to generate heat using a first current and the second heating element configured to generate heat using a second current; and
an electromagnetic (EM) radiation reducing device configured to reduce electromagnetic emissions from the first heating element and the second heating element, the EM radiation reducing device having a first electromagnetic (EM) radiation reduction element positioned adjacent to a first side of the heater and a second EM radiation reduction element positioned adjacent to a second side of the heater, wherein the first EM radiation reduction element has an elliptical curvature and geometry based at least in part on the heater.
