Scalable Modeling of Human Blockage at mmWave Human blockage at millimeter-wave frequencies is most commonly modeled through Knife-Edge Diffraction (KED) from the edges of the body shaped as a vertical strip. Although extensively validated in controlled laboratory experiments, the model does not scale to realistic 3D scenarios with many, randomly oriented bodies, on which multipath signals can be incident from any direction, not just normal to the strip. To address this, this article uses WaveFarer to investigate computational... (read more)Browse Modeling and Simulation Software Datasheets for Remcom (USA) -

A comparison between two 1.8GHz CMOS VCOs tuned by different varactors
It was found that circuit simulations (with Cadence simulator spectreS and bsim3v2 MOS model ) of the MOS- varicap VCO give oscillation frequen- cies between 10% and 20% lower than the measured fre- quencies. A more subtle problem derives from the lumped nature of the MOS spice model (Fig. 4).
