Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing EMP weapons face challenges in generating a large output electromagnetic pulse while minimizing diffusion, especially when deployed remotely or on aircraft, leading to reduced effectiveness and unintended wide-range influence.
Innovation Solution
An electromagnetic pulse irradiating system that condenses a laser beam to generate plasma at a light-condensing point near the target, using a pulse laser to increase electric field strength and generate a focused electromagnetic pulse, thereby minimizing diffusion and achieving a high output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the electromagnetic pulse is irradiated from a remote place to the target, then the constraints of size and weight are relaxed and large output electromagnetic pulse generation is easy, but the electromagnetic pulse diffuses during propagation and the strength declines
Solution Approach 1:
The patent introduces a reflective surface (mirror or satellite) as an intermediary to redirect and focus the electromagnetic pulse onto the target. This mediator enables remote irradiation while preventing diffusion through reflective focusing, resolving the contradiction between remote deployment and pulse concentration.
Solution Approach 2:
The patent utilizes the spatial dimension by positioning the electromagnetic pulse generation device remotely and using a reflective surface to redirect the pulse along a different path to the target. This dimensional approach allows large output generation away from the target while maintaining pulse strength through geometric focusing.
2Object-affected harmful factors
If the electromagnetic pulse is irradiated from the neighborhood of the target, then the diffusion of electromagnetic pulse is restrained, but the constraints of size and weight make large output electromagnetic pulse generation difficult
Solution Approach 1:
The reflective surface acts as a mediator that allows the electromagnetic pulse source to be positioned remotely (avoiding size and weight constraints near the target) while still achieving focused irradiation on the target, thus maintaining both low diffusion and high output capability.
3Reliability
If a laser beam is used to shoot down an unmanned drone, then the effectiveness is high, but a pilot is exposed to risk when the target is a manned aircraft
Solution Approach 1:
The patent employs a reflective surface to focus the electromagnetic pulse precisely on the target's electronic equipment, creating a localized effect that neutralizes electronics without affecting the surrounding area or exposing personnel to harmful radiation, thus achieving reliability while minimizing harmful effects.
Solution Approach 2:
The patent converts the potentially harmful broad-area laser irradiation into a beneficial focused electromagnetic pulse effect by using a reflective surface to concentrate energy only on the target's electronics, transforming a dangerous approach into a safe and effective one.

AI summary
A method of irradiating an electromagnetic pulse includes specifying a position of a target having electronic equipment; setting the light-condensing point based on the position of the target; and condensing the laser beam to generate plasma in the light-condensing point such that the electromagnetic pulse generated from the plasma is irradiated to the electronic equipment. In this way, a method and system for irradiating an electromagnetic pulse are realized which can irradiate the electromagnetic pulse of a large output while restraining diffusion of the electromagnetic pulse.
