GBPPR Microwave Oven & EMP Experiments


There is a really neat patent, number 6,343,534, which is titled "Landmine Detector with a High-Power Microwave Illuminator and Infrared Detector."  Here is the abstract:

"A hybrid remote-sensing apparatus is based on an active high-power microwave (HPM) illuminator and a passive infrared (IR) detector for the detection of shallow buried landmines. A 2.45 GHz, 5 kW microwave source is used for illumination and the thermal signature at the soil surface is detected in the 8-12 µm region both in near real-time as well as after a brief time-delay following illumination. The thermal signature at the soil surface is primarily made up of two components. A thermal signature occurs at the soil surface in near real-time due to the interference of the incident beam and the beam reflected by buried mines. A second thermal signature is generated when temperature contrasts due to differential microwave absorption by a mine and the surrounding soil are conducted upwards from that mine location to the surface. Both signatures are dependent on the complex dielectric constants of mines and the soil. These signatures can be used to determine the location of different types of metallic and non-metallic mine surrogates, dummy mines without explosives and live mines with explosives."

Basically, it involves using a RF magnetron, like that from a common microwave oven, to "heat" the soil in a particular area.  After a few minutes of RF heating, the area is then viewed using a infrared thermal camera to locate any "hot" spots.  Presumably, a landmine buried in the soil will retain some heat due to the dielectric absorption by the explosives inside the mine.  This would then be visible when viewed through the thermal camera, if it's not buried too far down.


This device doesn't appear to be too complicated to homebrew.  A person controlling the robot would have a little T.V. screen showing the video output from the thermal viewer.  If you locate any suspicious objects, you can then throw rocks at them from a safe distance.

The wireless video link and most of the power supplies are trivial to homebrew.

Robot chassis could be a radio controlled riding lawnmower.


Example photos from the above patent.  Figure 5a, 5b, 5c, and 5d are IR pictures of the sand surface over mine surrogates buried in moist sand at different depths which were taken at different times before and after irradiation with high-power microwaves.

  1. HERF 001  The purpose of this lab is to find a way to power a microwave oven magnetron from a portable power supply.
  2. HERF 002  This was my attempt at a high-power X-band frequency HPM device, using a high gain horn antenna, and a military magnetron.
  3. HERF 003  The reason I am constructing this lower power HERF that runs off the mains, is to experiment with microwaves and possibly dish reflectors.
  4. HERF 004  his project is a continuation of the HERF 003 project
  5. HERF 005  1 kW, 18 dBi high-quality HERF with tuneable waveguide.  This device was built as a demo for the 10th annual Information Warfare Conference in DC.  Lots of images, videos and a sneak peak at the 12 kW X-band battery powered HERF.  Videos of a PC being crashed.
  6. Explosively Powered EMP Device  Technical description of the principle behind explosive powered EMP weapons.
  7. Transient Electromagnetic Device (TED) HERF  Wideband transient electromagnetic device.
  8. HERF Radiation  Tests performed on a HERF device in order to graph its radiation pattern.  Great photos and radiation pattern images.
  9. Hand Held HERF  Power supply fits inside of the magnetron.
  10. Pulse Forming Network  Pulse forming network design and improvement.
  11. Radial Pulse Forming Network  This project is aimed at the design of a new bread of type-E pulse forming networks.


  1. Horn Antenna Designer  Helps design a rectangular horn antenna by showing how to cut pieces for it from sheet metal.
  2. Power Density Calculator  Calculates RF power density at a given gain and distance.
  3. HERF Range  Calculates and graphs HERF/HPM range at a given power and gain.
  4. Horn Antenna Calculator  MS-DOS application for calculating rectangular horn antenna dimensions.
  5. Focal Point Calculator  Calculates a parabola's focal point.
