  • Near Field Probes 30 MHz up to 3 GHz

    RF6 set - Langer EMV-Technik GmbH

    The RF6 near field probe set consists of 2 passive magnetic field probes and 2 passive E field probes for measurements in the development phase of the E-field and magnetic field in the range from 30 MHz to 3 GHz on electronic assemblies. The probe heads of the RF6 set allow a step by step localization of interference sources of the RF magnetic field and RF-E-field on an assembly. From a larger distance the electromagnetic interference is detected by RF-R 50-1 for the magnetic field and by RF-E 02 for the E-field. The RF-B 3-2 and RF-E 10 probes with their higher resolution can more presicely detect the interference sources of the magnetic field and the E-field. Field orientation and field distribution on an electronic assembly can be detected by special guidiance of the near field probe. The near field probes are small and handy. They have a sheath current attenuation and are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input.

  • Trifield Meter

    100XE - Alpha Lab, Inc.

    The Trifield Meter is a gaussmeter, electric field meter, radio field strength meter in a single unit. When measuring electromagnetic fields (EMFs), the primary concern is usually magnetic fields, which can be tricky to measure. If a less sophisticated 1-axis gaussmeter is used, a reading of zero could result even where the field is strong. A 1-axis meter must be oriented correctly to measure the field (which is a vector). The 3-axis Trifield Meter solves that problem by measuring the true strength of the field regardless of which way it is oriented. Therefore, the Trifield Meter can be scanned rapidly across an area without having to stop at each point to search for the orientation that gives a maximum reading. Another section of the meter detects AC electric fields, which can exist independently of AC magnetic field. The third section detects radio/microwave, such as from a leaky microwave oven.

  • Response Surface Modeling of an Actuator

    Simulink® with MagNet - Infolytica Corp.

    Modeling an electromagnetic actuator in a systems context is sometimes required to accurately simulate the dynamic interaction between drive circuit, actuator, and load. Co-simulation, where a systems simulator and MagNet run parallel transient solves, is one method that can be used. An alternative approach, Response Surface Modeling (RSM), creates a functionally equivalent model of the actuator by performing a large number of static analyses at different currents and positions. Presented here is an example of an RSM, used in conjunction with the Simulink system simulator from The MathWorks, Inc. The procedure is automated with the System Model Generator, which drives MagNet to execute its static solver and generates a file containing the RSM data. A plug-in to Simulink reads this file and provides a system block that can be connected to the rest of the system.

  • EM Explorer

    EM Explorer

    EM Explorer is a 3D electromagnetic (EM) solver for scattering problems of periodic structures illuminated by arbitrary incident fields including planewaves, Gaussian beams and focused Hi-NA beams. It can simulate both complex dielectric and complex magnetic materials including left-handed materials (LHM) that have a negative refractive index. EM Explorer is largely based on the same method of Finite Difference Time Domain (FDTD). Therefore it inherits most of FDTD's advantages and disadvantages. The advantages include simple & robust numerical algorithm, versatility for nearly any geometries, and good scalability of computing resources as a function of simulation volume size. The disadvantages are numerical dispersion and stability constraint due to the finite difference (FD) approximation to Maxwell's equations and explicit time marching algorithm.
