Dear List Members,
At an EMC lab several years ago I was shown that to properly check for
continuity of metal shielding and parts that one needed to just set the probes
of an Ohm meter on the surface to be measured, Do not push the probe tips into
the surface.
Could anyone point to a standard

all:thanks for your time and response.
I understand the frequency range we worry about (30MHz - 2GHz), any metal
(or metallized plastic) would be overkill and effect of apertures

hello:
as we know, threre are two main component of shielding effectiveness.
(Absorbtion and Reflection). is there any way to find out.. what percentage
of overall
Vijay,
Check out FloEMC, http://www.floemc.com/. You can have the software
determine this by integrating the losses in the material, whether they are
resistive or dielectric to find the absorption.

thank you in advance.

the thin-walls and hence, an efficient EMI shielding.
The main features of this thin sheet should be:
-Material: Bronze-Beryl (or maybe Copper-Beryl)
-Great elasticity, to overcome the differences in height of the
thin-walls.
-It mustn´t become deformed after pressing it.
-Application
