NECPP.jl

Author: Ritchie Lee (ritchie.lee@sv.cmu.edu)

This is a Julia wrapper for the necpp python package (https://pypi.python.org/pypi/necpp) The python package itself is based on NEC++ (https://github.com/tmolteno/necpp) Main documentation page of original package is at http://tmolteno.github.io/necpp/index.html

Installation

NECPP.jl uses PyCall.jl to wrap the python functions.

First install Python on your system (e.g., Python 3.5), then run pip install necpp Test that you can import the module in Python.

In Julia,

• ENV["PYTHON"] = "path/to/your/python.exe"
• Pkg.clone("github.com/rcnlee/necpp.jl", "NECPP")
• Pkg.build("PyCall")

Usage

To make the package function available:

using NECPP

Example

An example file is available under example/test.jl, that mirrors the test.py example in the original necpp repo (https://github.com/tmolteno/necpp). To run the example,

cd(Pkg.dir("NECPP/example"))
include("test.jl")
frequency_response()

which should output the impedance of a wire antenna at various frequencies.
