logperiodic_opt.py problems corrected #14
Description
Dear Tim Molteno - thank for sharing your necpp/PyNEC package. I am starting to learn using them. I have previously used nec2++.
Unfortunately I encountered some problems with logperiodic_opt.py - and it seems that I have corrected them.
My installation:
$ pip freeze
cycler==0.10.0
kiwisolver==1.1.0
matplotlib==3.0.3
necpp==1.7.3.5
numpy==1.18.0
PyNEC==1.7.3.4
pyparsing==2.4.6
python-dateutil==2.8.1
scipy==1.4.1
six==1.13.0
$
$ python -V
Python 3.5.9
$
I encountered the same exception as #11 :
$ python /Volumes/.../logperiodic_opt.py
Wavelength is 0.1224m, initial length is 0.0612m
Unoptimized antenna...
Traceback (most recent call last):
File "/Volumes/.../logperiodic_opt.py", line 225, in
show_report(initial_l1, initial_x1, initial_tau)
File "/Volumes/.../logperiodic_opt.py", line 168, in show_report
nec = geometry_logperiodic(l1, x1, tau)
File "/Volumes/.../logperiodic_opt.py", line 30, in geometry_logperiodic
nec.set_extended_thin_wire_kernel(True)
File "/Volumes/.../context_clean.py", line 104, in set_extended_thin_wire_kernel

File "/opt/local/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/PyNEC.py", line 181, in set_extended_thin_wire_kernel
return _PyNEC.nec_context_set_extended_thin_wire_kernel(self, ekflag)
TypeError: in method 'nec_context_set_extended_thin_wire_kernel', argument 2 of type 'bool'
$
It was corrected in "context_clean.py" by changing:
def set_extended_thin_wire_kernel(self, enable):
if enable:
debug ("EK", 0)
self.context.set_extended_thin_wire_kernel(1)
else:
debug ("EK", -1)
self.context.set_extended_thin_wire_kernel(0)
to:
def set_extended_thin_wire_kernel(self, enable):
if enable:
debug ("EK", 0)
self.context.set_extended_thin_wire_kernel(True)
else:
debug ("EK", -1)
self.context.set_extended_thin_wire_kernel(False)
Alternative (untested):
def set_extended_thin_wire_kernel(self, enable):
if enable:
debug ("EK", 0) # "0" is bool value?
else:
debug ("EK", -1) # "-1" is bool value?
self.context.set_extended_thin_wire_kernel(enable)
Next problem:
$ python /Volumes/.../logperiodic_opt.py

$
It was corrected in "logperiodic_opt.py" by changing:
dipole_center_segs[dipole_tag] = nr_segments / 2 + 1
to:
dipole_center_segs[dipole_tag] = int(nr_segments / 2 + 1)
Next problem:
$ python /Volumes/.../logperiodic_opt.py
Wavelength is 0.1224m, initial length is 0.0612m
Unoptimized antenna...
Initial impedance: ( 68.7, +15.2I) Ohms
Traceback (most recent call last):
File "/Volumes/.../logperiodic_opt_k.py", line 233, in
show_report(initial_l1, initial_x1, initial_tau)
File "/Volumes/.../logperiodic_opt_k.py", line 181, in show_report
print("VSWR @ 50 Ohm is %6.6f" % vswr(z, 50))
NameError: name 'vswr' is not defined
$
It was solved by adding some lines to "antenna_util.py":
comment: https://www.spectrum-soft.com/news/fall2009/vswr.shtm
comment: VSWR = (1 + Γ)/(1 - Γ)
def vswr(z, z0):
refcoef= reflection_coefficient(z, z0)
return np.abs((1+refcoef) / (1-refcoef))
Found a cosmetic feature in "logperiodic_opt.py":
dipoles_count = 5
ax.set_title("Gains of a 5-element log-periodic antenna")
but this statement text has 6-elements/dipoles:
ax.set_title("VSWR of a 6-element log-periodic antenna @ 50 Ohm impedance")
Should be:
ax.set_title("VSWR of a 5-element log-periodic antenna @ 50 Ohm impedance")
Succes!:
$ python /Volumes/.../logperiodic_opt_k.py
Wavelength is 0.1224m, initial length is 0.0612m
Unoptimized antenna...
Initial impedance: ( 68.7, +15.2I) Ohms
VSWR @ 50 Ohm is 1.504232
