RF Architectural Shielding Products
EMI (Electromagnetic Interference) is often used interchangeably with RFI (Radio Frequency Interference). However, EMI can be any frequency of electromagnetic noise, whereas RFI is a relatively narrow range of electromagnetic noise on the EM spectrum. EMI Shielding can be used to mitigate electric and magnetic radiation across various spaces. Radio Frequency (RF) Shielding can be used to mitigate RFI with specifically designed enclosures that can block RFI. As well, RF Shielding can include application of RF Shielding paints, fabrics, and other materials.

Sputter Coater & Freeze Fracture Solutions
To obtain high-quality images of samples with scanning (SEM) or transmission electron microscopy (TEM), your samples need to be conductive to avoid charging. If a sample does not have a high enough conductivity, then you can quickly cover it with a conductive layer using the method of sputter coating. Also, a carbon or e-beam evaporator coating can be used. Such coatings protect the sample, allow enhancing of the EM image contrast, or can act as a TEM-grid support film for small scale samples.

Electron Diffraction System
Modern physics is the post-Newtonian conception of physics. It implies that classical descriptions of phenomena are lacking, and that an accurate, " Modern", description of nature requires theories to incorporate elements of quantum mechanics or relativity, or both. This section includes many of the most important experiments in physics, including e/m tubes, the Franck-Hertz experiment, and nuclear magnetic resonance (NMR)

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.

WIPL-D Pro
WIPL-D kernel is unique in many ways, allowing the most efficient full wave EM simulations. It is based on the Method of Moments (MoM) but applied to quadrilateral mesh elements. In addition, the basis functions are HOBFs (Higher Order Basis Functions) which means up to 2 lambdas large mesh elements. The electrical size of problems is expressed in number of unknowns, rather than in mesh elements. The quad mesh offers two times less unknowns than the traditional triangular one, while using HOBFs reduces number of unknowns several times.
