EMP Shield Scam - Page 1 - EEVblog
2019年5月23日 · The EMP Shield monitors the voltage in the system as a whole. No matter where the volt in the system comes from the system as a whole will rise and fall at the exact same time. Because of this the EMP Shield only needs to be a part of that system.

EMP Protection for Your Car! - Page 1 - EEVblog
2023年1月19日 · This is why 'actual EMP protection' is cage-encompassing. If you took a cell phone, and suspended it in a 1/4" welded wire cage (think 'rabbit cage') by rubber bands, then grounded the cage to 'earth', the EMP cascade would follow the lowest impedance path to ground...it would 'circle the cage' and 'avoid the high impedance path through the phone'.

Shielding -- Is it effective when floating? - Page 1 - EEVblog
2014年4月3日 · By tying the shield to an appropriate part of the circuit this effect is reduced. Now the whole system changes in voltage when the shield acts as an antenna and so differential voltages between the shield and the circuit are minimized. What the shield is basically doing is acting as an equi-potential bonding system.
Is galvanized corrugated metal roofing ok for a heat shield
2014年9月14日 · Just putting the finishing touches on my wood fired sauna and am wondering if galvanized metal is suitable for a heat shield. Wondering about potential of nasty off gassing due to the galvanizing process, especially in a hot confined space ?
Non factory heat shield for mantel | Hearth.com Forums Home
2010年9月21日 · I just put in an order for an Avalon Ranier 45 insert and I'm going to need a heat shield for the mantle but want to avoid the need to use the surround panels. The guy at the shop said I could go to a sheet metal fabrication place and have a custom shield created that would be more attractive and doesn't require use of surround panels.
