In this paper, we derive an explicit formula for the voltage-to-voltage transfer function of multiple-input multiple-output (MIMO) wireless channels. A statistical model, the random coupling model, is used to develop the open-circuit transfer function of the MIMO channel on a physical basis. The emulation of realistic wireless channels is typically performed through irregular cavities with high losses...
In this paper, we compare different methods to determine correlation. First, we did analytical study on correlation of two parallel dipoles. We present two methods for analytical correlation calculation. In addition, the effect of source impedances is also studied. It is found that these two analytical methods result in the same correlation, and that source impedance matched to embedded element impedance...
A novel method of predicting the worst-case noise of a power distribution system is proposed in this paper. This method takes into account the effect of the transition time of load currents, and thus allows a more realistic worst-case noise prediction. A dynamic programming algorithm is introduced on the time-domain impulse response of the power distribution system, and a modified Knuth-Yao Quadrangle...
In this paper, an efficient parallel flow for the design of the full power distribution network (PDN) is proposed. The analysis demonstrates the impact of the voltage regulator model in both frequency and time domain response. Based on the experimental results, it is observed that including the voltage regulator model in the PDN model increases the transient voltage drop and PDN response which need...
It has previously been shown that radiation efficiency and input reflection coefficient S11fs of small antennas in free space can be obtained from measurements in reverberation chamber. The S11fs is obtained by so-called complex stirring of the S11 measured when the antenna is in the chamber. In the present paper it is shown that the accuracy of S11fs can be very good even for larger directive...
In this paper, we propose an efficient flow for the analysis and co-design of large 3D power distribution networks (3D PDN). In this flow, the network is modeled in frequency domain and thus can take advantage of parallel computing. The proposed flow significantly reduces the CPU time while obtaining accurate results as compared to commercial simulation tools. In the established 3D PDN model, we incorporate...
