# armmwave
Code that calculates transmittace and reflectance of materials at millimeter
wavelengths.
This software was developed to aid in development of anti-reflection coatings
for millimeter-wave optics---specifically, for optics used in Cosmic Microwave
Background (CMB) experiments. CMB experiments have begun to adopt
high-refractive index materials for their lenses. While there are many perks to
this optical design, there are also a few drawbacks. One of these is reflection.
High-refractive index materials---such as aluminum oxide and silicon, both of
which are used in CMB experiments---reflect a significant fraction of the light
that fall on them. To reduce that fraction we create anti-reflection coatings to
cover the lenses.
One way to make a coating that operates over a wide range of frequencies
(wavelengths) is to stack layers of different dielectric materials. Working out
the transmittance and reflectance of a multilayer dielectric structure is a
problem that can be handled using the characteristic matrix method. Enter
`armmwave`.
Please note: This code is under active development. While it has been verified
against experimental spectroscopic data (~25 to 500 GHz; examples will be
uploaded soon), make sure you understand the intricacies of your specific data
or model.
# Examples
`armmwave` provides a means to set up and evaluate models of multilayer
dielectric media. To do this, create one or more `Layer`'s (with associated
refractive index and thickness---and an optional loss term), create a `Source`
layer and `Terminator` layer (which are required for bookkeeping), and a
`Model`. By default, reflectance and transmittance is calculated between 500 MHz
and 500 GHz, but you can change this if you want. Here's an example model of a
sheet of ceramic material (in this case aluminum oxide) in a vacuum:
```python
import armmwave.layer as awl
import armmwave.model as awm
# First create a list of layers (dielectrics) in the order
# they should be evaluated
layers = [awl.Source(),
awl.Layer(rind=3.1, thick=2e-3), # thickness in meters
awl.Terminator()]
# Now create the model framework, feed it the layers, and run!
model = awm.Model()
model.set_up(layers)
results = model.run()
```
`model.run()` returns a dictionary with three keys: `frequency`,
`transmittance`, and `reflectance`.
# Contribution guidelines
This code is under active development. If you have an idea for a feature or use
case, please open an issue ticket. Let's talk! If you have an idea and you've
already written the code---that's great! Create a pull request and we can go
from there.
## Bugs
Let's face it: there are probably bugs. If you find one, please open an issue
ticket. Include a description of the issue and, if possible, a minimal working
example. I appreciate your patience (and your help).
# TODO
* Figure out how to make TravisCI make wheels for me
* Better docs
* Examples
