  • Patent number: 10684320
    Abstract: Provided is a method of evaluating a performance of a suspended channel plasma wave device (PWD) to evaluate a terahertz emission possibility of the suspended channel PWD based on physical properties of the suspended channel PWD. The method includes an x-axis setting operation of setting an electron drift velocity to be an x-axis; a y-axis setting operation of setting a plasma wave velocity to be a y-axis; and a device performance determining operation of determining an operation of a device by generating a design window based on a plasma wave generation condition of the suspended channel PWD and a relational expression between the plasma wave velocity and the electron drift velocity.
