An apparatus for using microwave energy for treating an infected site infested with insects or other small pests is disclosed. The apparatus comprises a source of microwave energy connected to a power source and a power controller, a transmission element, and an antenna. The apparatus can also comprise an isolator to protect the source of microwave energy. Methods to use such an apparatus for treatment of an infected site are also disclosed.

Apparatus for using microwave energy for insect and pest control and methods thereof

An apparatus for using microwave energy for treating an infected site infested with insects or other small pests is disclosed. The apparatus comprises a source of microwave energy connected to a power source and a power controller, a transmission element, and an antenna. The apparatus can also comprise an isolator to protect the source of microwave energy. Methods to use such an apparatus for treatment of an infected site is also disclosed.

A variable microwave power divider which includes an orthomode transducer having a first section capable of supporting a vertically polarized wave and a second section capable of supporting two orthogonal linearly polarized waves. Suitable probes for inserting or extracting RF energy are coupled to each section. A similar orthomode transducer is connected to the first transducer through a circular hollow waveguide with the transducers being angularly offset from one another a predetermined angular amount. A septum is positioned within the waveguide which is fixed thereto at one end with the other end being controlled to a predetermined spiral configuration in order to direct RF energy flowing through the waveguide to the sections of one transducer in a determinable manner.

Variable power divider

A suspension and drive system for a mechanical microwave power divider for spacecraft applications. The mechanical power divider includes a control which extends longitudinally therethrough. Torsion springs connect each end of the control rod to fixed surfaces and an electromagnetic control is coupled to the control rod to rotate it to a predetermined angular position. A selectively energizeable friction brake surrounds at least a portion of the control rod for holding it in a predetermined angular position.
