โœฆ Synopsis

The solubility parameters of a BMC composite material, its polyester matrix, and its low profile additive [poly(vinyl acetate)] were determined by using several methods. For Hildebrand's solubility parameter : calculation from molar additive laws and determination from unrelaxed elastic constants, these latter being determined from the propagation rate of ultrasonic waves. For partial solubility parameters from sorption test in saturated solvent atmosphere, using bidimensional solubility maps. The effect of glass fibers and mineral fillers on solvent absorption can be considered negligible. In contrast, the presence of the low profile additive significantly modifies the solubility parameter values.

## Conclusions The suitability of radial microstrip and slot-line stubs for the realization of broadband microstrip-to-slot-line transitions has been demonstrated. A simple procedure has been utilized to estimate the length of the slot-line radial stub for which an analytic model is still lacking.
