The capacitance of a varicap diode varies as the reverse voltage to the diode changes. As you increase the reverse voltage, the capacitance decreases. And vice versa.
I think you you are asking about varactor diode. varactor means variable capacitor. varactor diode is a p-n junction diode which provide a capacitance across it subjected to applied forward and reverse bias. means it provide variable capacitance which depends on the applied reverse voltage(mostly varactor diode works on reverse voltage).They are also known as varicap
Backward diode
A: A zener is a diode that when connected in the reverse mode current direction it will breakdown to a predetermined voltage any further increasing voltage the breakdown will remain practically the same.

It is called a varactor or a varicap diode. Its capacitance varies nonlinearly with the reverse voltage applied to its terminals.

by using a suitable diagram, explain the one of the operation in microwave energy sources except Guinn Diode.
Reverse-biased ---from the book of Malvino
The VI characteristics of PN junction diode when used as a diode rectifier are reverse bias and rectification is shown by an asymmetrical current flow.
Overlord was the code name for the invasion of Europe. D Day was the first day of the operation.
