• Simulation Of MIMO Handset Antenna Array Performance With Varying Hand Positions

  Performance of a 12-port handset antenna array operating in LTE bands 42/43 (3400-3800 MHz) and band 46 (5150-5925 MHz) is analyzed in XFdtd for varying hand hold positions on the device.  The results computed include S-parameters, Gain, Efficiency and Envelope Correlation Coefficient.

• Electrostatic Discharge (ESD) Simulation And Prediction For RF Devices

  ESD testing requires the use of many hardware prototypes, which is time consuming and expensive.   The ability to simulate the ESD testing process and pinpoint locations in wireless devices susceptible to ESD damage would be extremely valuable and allow engineers to reduce the number of prototypes required to design products for minimal ESD damage.  This presentation introduces a multiphysics-based ESD capability in Remcom's XFdtd that analyzes ESD testing via computer simulation.  This will save companies time and money by allowing ESD protection to be optimized during the design phase, thus reducing the number of prototypes required to be built and tested.

• Ten Cues You Need A 5G MIMO Channel Modeler

  How does Wireless InSite differ from planning tools? The most important differences emerge when users need to simulate 5G millimeter-wave and MIMO systems. This paper presents 10 cues that your organization may need a channel-modeling tool to supplement your 5G network planning efforts.

• WiFi Performance In A House with Two Routers

  Wireless InSite’s Communication System Analyzer provides capabilities for assessing the performance of LTE, WiMAX, 802.11n, and 802.11ac systems. The following example investigates WiFi throughput coverage in a house provided by 802.11ac routers operating at 5 GHz using an 80 MHz bandwidth.

• RCS of Hellfire Missile Using Remcom's Accelerated X3D Model

  Accurate calculation of RCS at millimeter wave frequencies requires sufficiently detailed geometric representation of the target and physical modeling techniques that capture the scattering effects of small facets.  Highly detailed facet models and traditional methods for calculating RCS at these frequencies can often result in very long run times.  Using Remcom’s X3D with Physical Optics (PO) and Method of Equivalent Currents (MEC) model for calculating RCS, accurate results can be achieved within reasonable run times.

• Configurable Array Antenna Simulation For Base Stations

  In this app note, a MIMO antenna is created and simulated to generate return loss, coupling, and gain patterns for several different configurations and operating modes of the device. The ability to form either omni-directional or focused beams is also demonstrated.

• Waveguide Examples Using XFdtd®

  Remcom's XFdtd software is well-suited for any microwave device design or analysis task.  This Waveguide Examples booklet showcases a collection of five different waveguide applications with downloadable project files.

• mmWave Channel Modeling With Diffuse Scattering In An Office Environment

  To accurately predict channel characteristics for millimeter wave frequencies, propagation modeling must account for diffuse scattering effects. This example uses Wireless InSite’s diffuse scattering capability to perform simulations of an indoor wireless network.

• Accelerating EM Simulations With MPI + GPU: Performance Study And Hardware Comparisons

  With Remcom’s XFdtd EM Simulation Software, there is no limit to the resources you can exploit to solve your EM calculations. By running approximately 160 simulations on NVIDIA’s PSG Cluster, we demonstrate the pros and cons of different combinations of equipment and techniques, including cost considerations for those researching available hardware.

• 5G Massive MIMO Outdoor Communications Analysis

  In this example the signal transmission between a massive MIMO base station and a mobile device located in downtown Rosslyn is analyzed using Wireless InSite’s MIMO capability.
