Penetration of Electromagnetic Wave Through EMI Gasketed Seam,a wave impinged on the barrier) and the transfer impedance of the EMI gasketed seam to predict the value of the . and . fields at any distance from the seam. An example using a high intensity field (field strength of 3770 volts/meter) that penetrates a gasketed seam. The result is the value of the .

Radiated Field Strength from Radiating Elements,y that the electromagnetic wave radiating from a transmission line pair of wires is generated by displacement current created by the difference in voltage between the wire pair and (2) prove that the impedance of high impedance sources of a wave provides the same level of impedance.

Optimal Use of EMI Gaskets,hielding as a function of screw spacing and the wavelength of any frequency of interest. The test requirements for a design engineer to properly select an EMI gasket for a specific application are listed. These include (1) the conductivity of the gasket against any of the materials and finishes used

Review of Current Test Methods Used to Grade EMI Gaskets by the Industry,n MIL-DTL-83528, and transfer impedance per SAE ARP-1705. The transfer impedance test method provides accurate test data of ± 2 dB over the frequency range of 10 kHz through 18 GHz. In the performance of the testing, the test plates are constructed from the materials and finishes used by industry. T

Silver Elastomeric Specification MIL-DTL-83528,can have a short storage and useful life. Reference to Appendix A is given. The appendix outlines six of the paragraphs that need revisions to accurately describe the silver elastomeric products. The revised paragraphs deal with: (1) the shielding effectiveness test data can be highly inflated (the

NEEDY

Shielding Effectiveness Theory of Shielding,based on wave theory and the analogy between transmission lines and the penetration of a wave through a barrier. A detailed analysis, comparing the value of the current delivered to a load impedance using circuit theory and wave theory, is conducted. The results of the analysis illustrate that for w
