This paper investigates the properties of the on-wafer interconnects built in a 0.18m CMOS technology for RF applications. A scalable equivalent circuit model is developed. The model parameters are extracted directly from the on-wafer measurements and formulated into empirical expressions. The expressions are in functions of the length and the width of the(More)
Reducing the gap between two metal nanoparticles down to atomic dimensions uncovers novel plasmon resonant modes. Of particular interest is a mode known as the charge transfer plasmon (CTP). This mode has been experimentally observed in touching nanoparticles, where charges can shuttle between the nanoparticles via a conductive path. However, the CTP mode(More)
We demonstrate near field enhancement generation in silver nanoantenna-superlens systems via numerical modeling. Using near-field interference and global optimization algorithms, we can design nanoantenna-superlens systems with mismatched permittivities, whose performance can match those with matched permittivities. The systems studied here may find broad(More)
The ballistic regime gives the upper limit of an electron device performance. This paper proposes a fast and efficient model for calculating the current–voltage characteristic of a cylindrical nanowire within the framework of the non-equilibrium Green’s function. Under certain assumptions, the calculation is simplified to a one-dimensional problem and the(More)
An improved subcell FDTD model is developed and reported in this paper for efficiently simulating a super-thin current sheet. By fully incorporating in calculation the surface currents previously-ignored, the algorithm proposed herein thus represents a more general and precise approach for thin-sheet modeling than the traditional subcell scheme that has(More)
A model development methodology for complex shaped on-wafer interconnects is presented. The equivalent circuit of the entire interconnect is obtained by cascading basic subsegment models.

A modified model for RF interconnect bends on lossy substrate in CMOS technology is presented. The model parameters are extracted directly from the on-wafer S-parameter measurements.
