Simulated Scattering Parameter Dataset for a Randomly Generated Non-Parameterized Microstrip Bandpass Filter between 1 and 10 GHz

The data set is comprised of two main components, a topology and a response, where each entry holds a topology and its corresponding response. The topology is a 32 x 32 binary image (and accompanying 32 x 32 binary array) where each pixel in the image represents the existence, or lack thereof, of conductor on the patch of the simulated model. The simulated model is created as a micro-strip filter with a 16 mm square patch placed in between 2 perpendicular 50 Ohm feed lines. The simulated model uses a 1.6 mm thick, 30 mm wide, square FR-4 substrate and a ground plane. The response of an entry contains the simulated electrical response of the simulated model, when the model’s square patch is updated to represent the entries topology, each pixel in the image represents a 0.5 mm square on the patch. The electrical responses recorded are the scattering parameters, more commonly known as the S parameters, the reference impedance and the frequency points at which the previous two parameters were calculated, 5001 points between 1 and 10 GHz. All electrical responses were created using the same simulation setup in CST Studio Suite.

Each set of topologies, or each file contained within the two Topologies folders, are generated by iteratively sampling a topology distribution. A topology distribution refers to a set of parameters, parameter ranges and the probability distributions within these ranges. The choice of considered topology distributions, found in the Considered Topologies folder, are based off the electromagnetic response of an empty model, or a model with no topology added and perturbation theory.

The 4 folders in this data set contain:
MATLAB -> An example script to use the data set in MATLAB.
Python-> An example script to use the data set in Python.
Considered Topologies -> 800 entries used for data analysis containing 100 entries of each considered topology (X, Rotated X, Rotated Noisy X, Slash, Rotated Slash, Rotated Circle, H, and Y).
Final Topologies -> 5000 entries created in response to the diversity analysis of the Considered Topologies, namely 3000 Rotated Noisy X and 2000 Rotated X.
Scripts -> All MATLAB scripts and CST model required to recreate this dataset.

Each file contained within the Considered and Final Topologies folders uses the file name structure <topologyIndex_topologyType-numberOfEntries.mat>, where topologyIndex is used to differentiate between 2 files containing the same topologyType.

Both Considered and Final Topologies folders contain an Images folder; each topology is saved as an image to make it easy to find specific topology using the file name
<topologyIndex_topologyType_imageIndex.png>. The images name is also stored as an additional field in each entry, in each topology set.
