radio frequency shielding by Zn and Al
Dear All,

I have read from several sources that Zn is a radio frequency shielding material, from this information can I conclude that Zn would not be deected by radar or it will have a low magnetic signiture?

I also would appriciate information about the radio frequency interference and electro magnetic interference info of Al.

I am trying to comment on the applicability of TS zinc and aluminum on naval vessels.

Thanks to all inadvance,

Best Regards;

UBG

Hi basakglkn

Radio frequency interference RFI shielding is really only necessary on non-electrically conductive material enclosers of sensitive electronic devices. The coating property that is important is electrical conductivity. Steel enclosers would not benefit from a zinc coating.

If you are thinking of shielding the internal electronics of a vessel constructed of fibre reinforced plastic or wood (non-electrical conductive structure) then Zn and Al would be effective. I have my doubts as to whether these coatings would provide any or significant "stealth" effect from being detected on radar though.

Edit:

with respect to RFI and EMI. Obviously it would benefit from anti-corrosion Happy0193

I had carried out some expiremental work on RFI and EMI shielding FRP cabinets used for defense equipments. How ever I could not find out final out come of this work as it was classified.
