A world record: 5 decades of constant phase angle

PhD student Agamyrat demonstrates the potential of the Fractional-Order Capacitors(FOCs) fabricated using MoS2-ferroelectric polymer composites in robust and accurate realization of various electrical systems. A molybdenum disulfide (MoS2)-ferroelectric polymer composite is used to design/fabricate a FOC. The resulting FOC's bandwidth of operation, which is defined as the frequency band where the variation in the phase angle is no more than ±4° is five decades between 100 Hz and 10 MHz, a 3 decades improvement over the best-reported state of the art. The value of the constant phase angle can be tuned by changing the type of the ferroelectric polymer in the composite and the volume ratio of MoS2
