Directed energy weapons emit focused energy to damage targets. They include microwave and laser weapons. Microwave weapons use high-power electromagnetic pulses that can disrupt electronics over long ranges but have shorter effective ranges than lasers. Laser weapons use stimulated light amplification to form precise beams able to damage targets but can be reflected or absorbed. Both types of directed energy weapons offer advantages like accuracy, unlimited magazines, and all-weather use but also have disadvantages like potential deflection or absorption of beams and large construction requirements. They have applications as weapons for defense and offense and could be used to destroy missiles, aircraft, ships, and vehicles.

3. INTRODUCION
 After dacade of research and development DEW become a
operational reality such weapon generate stream of
elecromagnetic energy that precisely aimed over long
distance to disable or destroy target.
 Directed energy weapon is the most powerful weapon
In this century and it is the game changing technology in the
war.
 The electromagnetic spectrum is critical enabler for the
militaries.
 In future war will be won by whichever side best exploits the
electromagnetic spectrum.

4. WHAT IS DIRECTED ENERGY
WEAPONS?
A Directed Energy Weapon emits highly focused energy,
transferring that energy to a target to damage it.
Directed Energy Weapon are Most Advance and
Sophisticated technology with very distinct feature
compared to current kinetic energy Weapons.

5.  HIGH POWER MICOWAVES
 Ways to Achieve
 Capacitor Based Charging Process
 Inductor Charging
 Flux Compress Generator
 1) PULSE POWER SOURCE
Consist of Power Supply should Deliver short and intense
electrical pulses of 1 MVolt or more. It should have Pulse
Duration 1 Micro Second .

2) Parabolic
3) Hybrid

8. LASER WEAPONS
 Lasers have at least three common components:
• A lasing medium or an amplifying medium that increases the
intensity of the light beam (gas, liquid, solid, semi-conductor)
• A method of stimulation or pumping (pulse discharge, electricity,
or chemical reaction)
• A resonant cavity ( reflective mirrors)

 Difference Between LASER & HPM

12. ADVANTAGE OF DEW
 Pinpoint accuracy
 Low cost per use and main maintenance
 Unlimited magazine capacity
 Less lethal if tuned properly
 Operate in all weather condition
 Engage multiple target
 Speed of light operation
 They are silent
 Difficult to track

13.  HPM weapons has short range compared to Laser
 Laser can be Deflected, Reflected & Absorbed by
physical chemical property of material.
 Laser weapon require large construction.
DISADVANTAGE

14. APPLICATIONS
 Used as weapon for defense as well as offence
 DEW Laser can destroy missiles (ballistic, cruise),
ships, aircraft, drones if power is very high.
 Low energy laser can destroy only light armored
vehicles and drones
 The laser can be mounted aircraft, ships or any
ground vehicle such as tanks
 HPM weapons temporarily disrupt electronic
system or permanent damage to integrated circuit.

16. CONCLUSION
 Directed Energy Provide quick employment deep
clip capacity, scalability from lethal to non lethal
simplified pointing and tracking all weather
capability, multiple target engagement, and long
distance projection.
 They can also pass through walls without a trace.
 They are Silent provide surgical accuracy with speed
oh light.
