We consider bundles of conducting Carbon Nanotubes as antennas to operate in the sub-terahertz range of frequencies. A transcendental equation for the complex propagation parameter of the electric current on the antenna is derived. Therefore, the resonant length of the antenna is obtained along with the radiation resistance and the radiation efficiency. Both the single wall (SWCNT) and the multiple...
We present the design of an analog circuit which solves linear programming (LP) or Quadratic Programming (QP) problems. In particular, the steady-state circuit voltages are the components of the LP (QP) optimal solution. The proposed method is used to implement a LP-based Model Predictive Controller by using an analog circuit. VLSI design of an LP problem demonstrates nanosecond range solution latency...
The electrical-thermal co-simulation approaches, for wires-in-air and wires-in-package, are developed by the coupling between their electrical and thermal properties, using ADS (Agilent Design System) Symbolically-Defined Devices (SDD) models for multiple wire segments. Key parameters for these simulation models are then derived from experimental results. These experimentally validated (or assisted)...
In this paper, a modified enhanced transmissionline theory taking into account higher-order modes is described. The new equations are based on the correction of the per-unit-length parameters that become frequency dependent and contain the radiation resistance. In particular, the per-unit-length resistance takes into account this radiation resistance and an additional resistance proportional to the...
The paper gives a critical analysis of recently proposed cut-insertion theorem. It is shown that all cut-insertion equivalent networks can be obtained using a simple extension of the substitution theorem. For example, using two voltage sources connected in parallel between a chosen and reference node, then cutting the wire between the voltage sources one concludes that a wire with a known voltage...
In lithography process, wafers need to be baked on the hot plate. There are very high requirement to the temperature uniformity of hot plate surface. To the problem of choosing design parameters, the orthogonal experimental design method was used, the simulation software ANSYS was applied, the design parameters on the various conditions were analyzed, Then a regression model was obtained based these...
One of the primary purposes of performing the steady-state analysis of a distribution feeder is to determine the voltages at every node. Because these voltages are a function of the line voltage drops it is critical that the line impedances used are as exact as possible. In 1926 John Carson developed equations that would determine the self and mutual impedances of any number of overhead or underground...
