#2Part of a Defcon talk a few years ago included something similar:

#3The article seems to confuse EMPs and continuous interference devices.
As far as I know, there is no viable way to make a particularly powerful EMP that can be used multiple times inside of a suitcase.
The only method I know of constructing a reasonably powerful portable EMP is by creating an EPFCG, which would be very dangerous to the operator inside a suitcase, is directional, and can only be used once.

#4http://blockyourid.com/~gbpprorg/mil/herf/voltsamps/herf005.... A HERF device is actually pretty simple to cobble together, if you don't mind size and high power consumption. Making it portable is more of an engineering challenge, but if you can purpose-build a magnetron rather than using one from a microwave oven, the problem becomes easier to solve.

Could you make a marx generator based EMP device that fits inside a suitcase I wonder?

Only the first sentence of the article mentions an EMP in a movie. The rest of the article is about continuous EM attacks, including interference but also damaging equipment.

#7Ah yes, I remember playing CyberPunk 2020 (RPG) long time ago, EM weapons were standard equipment. Interesting to see that the sci-fi is now becoming reality.

#8The Blumlien pulser is easy to fabricate and can generate very short rise times since you are charging up a coaxial cable to high potentials, then shorting one end to start the pulse.

#10You don't need batteries to make an EMP

The question is if the equipment is inside a Faraday Cage and the device is outside, will it affect it.
