Electromagnetic Express
EM-X
Is a physics modelling package for electromagnetic fields and charged particles. A CAD component allows the definition of mechanical parts and assignment of electric potentials, magnetization and charged particle sources. A time domain, particle-in-cell (PIC) tool then solves the electromagnetic fields and moves the particles within them. The particles’ own charges andmotions are fed back into the electromagnetic fields allowing the effects of space charge and selfmagnetism to be accounted for.

Test Fixture, Shielding Effectiveness
EM-2108 | 1.5 GHz – 10 GHz
The EM-2108 is a standard test fixture for evaluation of the electromagnetic shielding effectiveness (SE) of planar materials. The fixture is a section of coaxial transmission line broken to allow the insertion of planar test materials. Although ASTM D4935-10 is currently limited to an upper frequency of 1.5 GHz, the EM-2108 meets and complies fully with both the impedance and SE requirements called out in ASTM test method D4935-10 up to 10 GHz. These results are shown in Figures 1 & 2. The measured data relates to the shielding effectiveness due to a plane wave (far field EM wave) from which near field values for magnetic and electric fields may be inferred.

EM Tracking Products
The strength of the Aurora and 3D Guidance electromagnetic tracking solutions lies in their similarities and their differences. Both can provide unobstructed in-vivo tracking of OEM medical instruments, share exceptional measurement accuracy and reliability and are engineered and manufactured to deliver unparalleled tracking performance. Between them, there are seven different field generators with unique measurement volumes, and 20 standard sensor offerings (plus custom options). While the Aurora has 6DOF and 5DOF sensors, the 3D Guidance solution specializes in 6DOF tracking. 6DOF sensors are usually re-processable; 5DOF can be disposable. Some of our field generators are portable, while others seamlessly integrate into the medical OEM’s procedural cart or operative table. These differences provide near-countless opportunities to customize and integrate the Aurora and 3D Guidance solutions – all while benefiting from a shared foundation of technical excellence and expert product execution.

Inductive Sensors
Inductive Proximity Switches, self contained, depend on the output of an oscillator for their operation. The oscillator resonant circuit uses an open core coil to produce a concentrated high frequency electromagnetic (RF) field, which emerges from the active surface of the sensor. If a metal target (or other electrically conductive material) enters this field, eddy currents will be induced in it, causing the resonating oscillator to be damped.

EMF Measurements/EM Measurements/Electromagnetic Radiation
Holland Shielding Systems B.V.
Electromagnetic fields cause interference in electronic devices and may affect the health of people close to where the fields are generated. It is important to recognize this at an early stage in a construction process, for instance at a future construction location or while construction is already underway, so that budgets are not exceeded. By means of field-strength measurements one can chart the existing electromagnetic fields and radiation emitted by GSM, UMTS antennas and transformer spaces, to mention a few examples. These measurements can help determine the best location in the new building for rooms where sensitive measurements are to take place, e.g. in hospitals or nano laboratories. And last but not least, field-strength measurements can detect sources of interference and can be part of a scheduled check of existing screened spaces and Faraday cages.
