1. Application Example: Touchscreen 3x4 Diamond

    The capacitance matrices for a 3x4 touchscreen are analyzed in an unloaded and loaded case. Based on the changes in capacitance, the location of the 1mm stylus is identified.

  2. XFdtd Touchscreen Capacitance Computation Brochure

    Capacitive sensors measure changes in capacitance to detect differences in their environment.  They are commonly used as touchscreens to detect the location of fingers or a stylus on the screens of smart phones, tablets, computer screens, music players, and computer touch pads, though many other uses exist in scientific research and industry.  Remcom’s XFdtd EM Simulation Software can compute the capacitance of complex sensor designs, allowing the designer to choose the best geometry for their needs without prototyping.

  3. Application Example: Matching Network Design For GPS/ Bluetooth Antenna

    This application note describes how the XFdtd's Circuit Element Optimizer is used to determine optimal matching component values for a dual purpose antenna.

  4. Brochure: Full Wave Matching Circuit Optimization In XFdtd

    Determining the final set of component values in a matching network can be a challenging process.  XFdtd’s Circuit Element Optimizer simplifies and speeds the process of matching the antenna.

  5. White Paper: Overview Of XFdtd’s Circuit Element Optimizer

    XFdtd® 3D Electromagnetic Simulation Software is designed to analyze antenna and matching circuit structures using the full wave Finite-Difference Time-Domain (FDTD) simulation method. XF’s Circuit Element Optimizer utilizes full wave analysis of the software to select the component values for a given printed circuit board (PCB) layout.

  6. Benefits Of Time-Domain Electromagnetic Simulation For Automotive Radar

    The requirements for automotive radar sensors in common ranges - such as 24 GHz and 77 GHz - are becoming more stringent and engineers need to understand how design decisions affect performance.  

  7. Thermal Sensor In 64 MHz Birdcage Coil

    In this paper, a lowpass birdcage coil designed to operate at 64 MHz is simulated to show B fields in both unloaded and loaded conditions.

    This application example illustrates an antenna design for hepatic microwave ablation simulated in liver tissue. 

  9. XFdtd® Release 7 For the Biomedical and MR Community

    Ensuring that new devices meet regulatory and certification requirements is a necessity. Remcom's tools can greatly speed the design and certification process by allowing realistic simulations of device performance before the costly prototyping stage. Analysis options include device performance, such as tuning, and bio-interaction including SAR.

  10. Application Example: Lightning Strike on Wind Turbine

    In this example, the impacts of a lightning strike on a simplified wind turbine are compared for different strike locations by comparing the magnetic fields created inside the nacelle.
