For the offense, one would utilize electronic jamming, electronic deception, directed-energy weapons, and electromagnetic pulse weapons.
Data are beamed back to the surface by electromagnetic pulse or optical fiber.
To protect electronics infrastructure, entire systems must be encased in a metallic shield to prevent any external electromagnetic pulse from entering.

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.

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.

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.
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.

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.
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.
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.
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
He supports the development of measures to protect our satellites and other facilities against electromagnetic-pulse weapons.

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.
With each changing minute, an electrical pulse generates an electromagnetic field that changes the position of the crystals on the face of the watch, to elegantly display the passing time, while producing a distinctive sound unique to the Phosphor Reveal digital watch line.
