For the offense, one would utilize electronic jamming, electronic deception, directed-energy weapons, and electromagnetic pulse weapons.
This renders Iran capable of launching an electromagnetic pulse attack from sea against just about any country.
Data are beamed back to the surface by electromagnetic pulse or optical fiber.
Scientists studied the effects of an electromagnetic pulse from a high-altitude nuclear blast in depth during the Cold War.
To protect electronics infrastructure, entire systems must be encased in a metallic shield to prevent any external electromagnetic pulse from entering.
To protect electronics, an entire system must be encased in a metallic shield that prevents any external electromagnetic pulse from entering.
Specifically, they have or are developing the ability to engage in devastating electromagnetic pulse (EMP) attacks, biological warfare and other asymmetric terrorist strikes.
Large sun-grazing comets could bring on the sort of global electronics meltdown usually associated with electromagnetic pulse weapons or a full-scale nuclear exchange.
FORBES: Sun-Grazing Comets As Triggers For Electromagnetic Armageddon
An electromagnetic pulse or EMP attack is an indirect nuclear attack.
CENTERFORSECURITYPOLICY: An urgent memo to the next government
The EMP Threat Commission recommends steps be taken urgently to reduce that vulnerability by protecting electrical, water, telecommunications and other infrastructures against the crippling effects of electromagnetic pulse.
Military planners understand the vulnerability of the grid to upset, but have been more concerned with man-made threats such as the electromagnetic pulse that would be generated by a high-altitude nuclear detonation.
FORBES: Intelligence Community Warns Solar Storms Could Collapse Electric Grid
What if some day a rogue state--or even a traditionally friendly country turned enemy--decides to set off a nuclear device in space that results in an electromagnetic pulse destroying our ability to communicate?
Unfortunately, the lack of U.S. nuclear testing since 1992 has also contributed to uncertainty about the adequacy of steps to protect conventional military gear from the effects of high-energy, electromagnetic pulse (EMP) attacks.
Finally, Iran appears to have developed all but one of the ingredients needed to mount what has been described as a "catastrophic" attack on the United States: a strategic strike unleashing a high-altitude electromagnetic pulse.
Dr. Graham formerly served as President Reagan's Science Advisor and has in recent years chaired the congressionally mandated Commission to Assess the Threat to the United States from Electromagnetic Pulse (better known as the EMP Commission).
Believe it or not, Congress sought to address some of these questions when they established an EMP Commission in 2001, formally known as the Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack.
FORBES: 'Revolution' Depicts America After an EMP Blast: But Is It Plausible?
According to Andy Mazzara, the director of the Institute for Non-Lethal Defence Technologies at Pennsylvania State University, prototypes of such devices use a laser to create an ionised channel of air through which an electromagnetic pulse is directed.
This could allow Tehran to execute the sort of missile-delivered strike that has been judged by a congressionally mandated, blue-ribbon commission to be capable of causing "catastrophic" damage to the United States - an electromagnetic pulse (EMP) attack.
Not only would everything be devastated in the immediate vicinity of the blast but an EMP (electromagnetic pulse) could wipe out almost anything that uses electricity (including cars and battery-powered phones, radios, and flashlights) throughout a much wider area.
But Saxe's lab, using a machine called a transcranial magnetic stimulator, which applies an electromagnetic pulse to a targeted point in the brain, can temporarily disable the function in the TPJ and change what people think about someone else's actions.
The Times failed to mention the fact that a blue-ribbon, congressionally mandated EMP Threat Commission produced a number of studies confirming the reality of a scenario in which ballistic-missile-delivered high-altitude electromagnetic pulse attacks could occur, with "catastrophic" effects on the United States.
Scientists are gathered this week to discuss a relatively underappreciated threat to our well-being, the impact a huge solar flare (also known as a solar mass ejection (SME) or solar electromagnetic pulse (EMP)) directed at Earth could wreak upon our modern technology.
At the same time as the Obama administration is wreaking havoc on our nuclear deterrent, it is undermining the other insurance policy we need against catastrophic, potentially country-cratering attacks like thoseinvolving ballistic missile-delivered electromagnetic pulse strikes: effective national, or better yet global, missile defenses.
This is despite the fact that two congressionally-mandated commissions the Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack, and the Congressional Commission on the Strategic Posture of the United State have both previously warned of the danger of EMP.
These scenarios, of course, are likely because they compare favorably to the worst case scenarios in which a nuclear-armed Iran decides to simply detonate its nuclear bombs over Israel, either in the form of an electromagnetic pulse (EMP) attack or in the form of a direct nuclear strike.
If an aggressor launches a nuclear device of whatever size and detonates it above the atmosphere and in the line of site of its target country, the x-rays and gamma rays emitted by the blast will cause an electromagnetic pulse, or wave a million times stronger than the strongest radio wave.
CENTERFORSECURITYPOLICY: An urgent memo to the next government
As hearings before the House Armed Services Committee and a new "Backgrounder" by Jack Spencer of the Heritage Foundation entitled "America's Vulnerability to a Different Nuclear Threat: An Electromagnetic Pulse, " makes clear, a rogue state or other enemy could inflict grievous harm on an advanced society like America's by exploding a nuclear weapon high above the United States.
CENTERFORSECURITYPOLICY: Post-Mortem on the Summit: The Talbott Communique
Finally, there is the problem that even some Democrats on Capitol Hill - notably, Senator Joe Lieberman (technically an Independent who caucuses with Democrats) and Rep. Bennie Thompson, the chairmen respectively of the Senate and House Homeland Security Committees - recognize could eventuate at any time: an attack involving relatively short-range, ship-borne ballistic missiles used to launch a strategic electromagnetic pulse (EMP) attack against this country.
He supports the development of measures to protect our satellites and other facilities against electromagnetic-pulse weapons.
WSJ: Michael Ledeen: Santorum Was Right About Iran��When It Was Unpopular
By unleashing a massive pulse of electromagnetic radiation sweeping over the planet, a severe solar storm could potentially knock out the electric power grid, silence radio and satellite communications and disrupt GPS navigation systems.
