Interpolating wavelets in nonlinear devices modeling

A new approach to the simultaneous modeling of semiconductor devices and all the circuit elements is discussed in this paper. The electromagnetic wave propagation through semiconductor devices is modeled by the sparse point representation, based upon interpolating wavelets. A nonuniform mesh generated in this manner is fully adaptive, dynamic and object oriented. The solution is developed in the time-domain. An example of a device and simulations is presented. Numerical examples show substantial savings in computer memory for electrically large problems. Semiconductor diodes are discussed as examples.
