According to one aspect, the present invention relates to a method of manufacturing at least one non-uniform thickness composite spar component. The waveguide radiating element comprises a rectangular tube, which includes partially filled dielectric slabs that are disposed on parallel planes and incident on a lower edge of the element’s mouth. The oxide sols have not undergone any subsequent drying and the particles are believed to be substantially spherical in structure, dimensionally stable and do not change shape over time. Additionally, the monitoring addresses are assigned to the network interfaces for use by the monitoring process, with each of the monitoring addresses being assigned by being added as an additional network interface address of its network interface. In addition, a method for using the laser pulse stretching unit is also described herein.
