Exploiting Wave Transport in PT Symmetric Media

This thesis will present an integrated experimental and theoretical effort toward managing wave transport and introducing novel methods for signal manipulation. This will be achieved by developing a new circuitry design that exploits both absorption and gain mechanisms via judicious spatial arrangements of active elements that exhibit space-time reflection, or PT symmetries. We will show that the resulting structures, display intriguing behaviour that holds promises for the creation of new synthetic matter with novel functionalities. The playing field will be photonic and electronic circuits with complex potentials corresponding to complex refraction index and active impedances respectively.
