function YagiSimulate(handles)
% this function will export the final design to 
% superNEC for further simulation

% INPUTS: 
%   modelFreq: The frequency at which the SNEC structure is designed
%   obj.location: The location of the assembly 
%   obj.segLength: The segment length in wavelengths 
%   obj.orientation: The orientation of the assembly 
%   obj.freqScale: The factor by which the model freq. is scaled 
%   obj.spacing: The spacing between the elements 
%   obj.len: The length of the yagi elements 
%   obj.radii: The radii of the yagi elements
