In mathematics, subharmonic and superharmonic functions are important classes of functions used extensively in partial differential equations, complex analysis and potential theory. Superharmonic ...

Abstract: This article presents a 220-GHz cryogenic quasi-optical Schottky subharmonic in-phase quadrature (IQ) demodulation receiver for terahertz (THz) applications. To achieve spatial separation of ...

The error in a method's solution is defined as the difference between the approximation and the exact analytical solution. The two sources of error in finite ...
