This paper presents a novel Programmable Optically Variable Resistor (POVR) that provides a wide, continuously adjustable resistance range using an LED-LDR (Light Emitting Diode-Light Dependent ...
We present the design of a graphene-based electronically tuneable microstrip attenuator operating at a frequency of 5 GHz. The use of graphene as a variable resistor is discussed and the modelling of ...
