A power divider for a waveguide between a single electromagnetic microwave generator input and two output ports, the divider including two tuner networks, each comprising a moveable capacitive probe with a pair of fixed flanking inductive posts. Measurement information for the physical signal X may be received, where the measurement information includes information indicating a plurality of order components of the physical signal X. A plurality of lights are disposed on one or more of the first, second, and third arms. The structure is sintered at a temperature that exceeds the glass formation temperature of the bonding agent, but less than the maximum operational limits of the biosoluble fiber, to form a structure that has sufficient strength and porosity to provide for filtration andor as a catalytic host. By using the methods and apparatus, detached tissues can be preserved for greater lengths of time and are ultimately in a better condition for replantation surgery. The flexible circuit board which has an insulating film made of a thermoplastic resin, a wiring layer formed on the insulating film, and an insulating layer made of a thermoplastic resin and formed on the wiring layer.
