does cell phone radiation cause cancer?

Giant terahertz gain via surface plasmon polaritons in photoexcited grapheneSPIE NewsroomGraphene is a 2D material with one-atom thickness, in which collective charge density waves (called plasma waves) of 2D electrons and/or holes are excited by electromagnetic radiation. The energy of 2D plasma waves can be quantized as 2D plasmons….Giant terahertz gain via surface plasmon polaritons in photoexcited graphene – SPIE Newsroom
