     This package combines a number of advanced features and should not be used without knowledge and familiarity of the underlying techniques. It requires:
 
-    * Knowledge of Python to contruct a model input file to use with the optimisation
-    * Understanding of optimisation techniques in general, and in particular Taguchi's method
-    * Care and 'sanity' checking to be made throughout the process

-The bowtie design features 3 vertical slots (y-direction) in each arm of the bowtie. Each slot has different loading resistors, but within each slot there are 4 resistors of the same value. A resistor is modelled as two parallel edges of a cell. The bowtie is placed on a lossless substrate of relative permittivity 4.8. The antenna is modelled in free space, and an output point of the electric field (named ``Ex60mm``) is specified at a distance of 60mm from the feed of the bowtie (red coloured cell).
