This is a means of killing bed bug infestation in bed mattresses and other hard to treat areas that can handle exposure to microwave energy, yet the use of insecticides is not welcomed. The diagram gives a basic design layout for building a microwave transmitter to provide short-range microwave exposure to areas where bed bugs might be hiding. The device would be connected to a microwave generator next to an E-type T-section with two rectangular wave-guides leading from the T-section to the transmission horns on the end of each wave-guide section. The microwave energy being transmitted from the horns can then be applied to a local area in front of the horns. This would allow for radiated heating of the bed bugs, or any other similar infestation, providing a non-chemical means of killing the bugs. Each horn will transmit a wave that is 180 degrees out of phase when referenced to the emission seen from the other horn thereby canceling each other out due to the destructive interference that will occur when the two waves intersect. This 180-degree phase shift is developed with the E-type T-section within the system. This will isolate the microwave radiation to localized areas preventing interference in electronics outside of the immediate area.

In between the point of destructive interference where the two radiated waves intersect, and the emission points of each horn would be the area that would see radiated energy capable of heating the bugs to the point of death. Bed bugs are quite vulnerable to heat so even temperatures above approximately 120F would bring the bugs to the point of extermination.

This device is another tool that could be used to help gain control over the immense, growing bed bug infestation that is occurring in many parts of the world.
