<p>━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━<br> DATA DESCRIPTION README FILE FOR<br> "Towards probing for hypercomplex quantum mechanics in a waveguide interferometer"</p> <p> Sebastian Gstir<br> ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━</p> <p> 2021-09-07</p> <p><br> Table of Contents<br> ─────────────────</p> <p>1) Peres/Sorkin Measurements<br> 2) Interference Contrast</p> <p>With the given raw data, all figures and tables of our publication can be recreated. The data is saved in the Hierarchical Data Format (HDF5), which can be opened with various programms and programming languages like Mathematica and Python.</p> <p>The code used to process this data and perform the given shown simulations is not contained in this repository, but can be requested from the authors if required.</p> <p><br> 1) Peres/Sorkin Measurements<br> ══════════════════════════════</p> <p> The files '23degrees measurement.h5' and '30degrees measurement.h5' hold the measured raw data for a housing temperature of 23°C and 30°C, respectively (see chapter 4).<br> We measured the light passing through our chip for different shutter combinations and recorded multiple values for each combination. The set shutter combination is recorded in "/shuttercombination" as an integer (0 to 7), whose binary representation describes the state of each shutter ('0' ... close, '1' ... open). E.g. the shutter setting '3' is '011', which states that shutter A and B are open and shutter C is closed. The set of all eight settings is in this context called a cycle. As stated in the publication, we recorded multiple cycles with randomly ordered shutter settings.<br> For each shutter setting we recorded the temperature of the chip housing in "/temperature-housing" and multiple successive signals of the photodiode in "/PD signal", with the corresponding timestamps in "/time". Therefore, all datasets (PD signal, time, temperature housing and shutter setting) are three-dimensional. The first dimension is the number of shutter combinations, the second the index of measurements per combination and the third dimension is specific for each datatype (desribed by the 'unit'-attribute field of each dataset).<br> Product names of the used devices are stated in the corresponding attribute fields.<br> <br> In order to create the data given in our publication, like figure 2 and B1, we filtered the recorded data for shutter errors and outliers. The following gives the excluded cycle indices as a list sorted by shutter combination (from 0 to 7) for each measurement.<br> "23°C"-measurement: {{204, 222, 226}, Range[1, 80], {}, {}, {45, 65, 156, 226, 333, 366}, {121, 227, 341}, {46, 63, 252, 335, 376}, {}}<br> "30°C"-measurement: {{}, {186, 371}, {}, {47, 67, 149, 271, 335, 393}, {272, 444, 446}, {40, 424, 439}, {301, 410}, {51}}<br> If one cycle includes a shutter combination with an outlier or shutter error, we excluded the whole cycle.<br> <br> Note that in case of the "23°C"-measurement no housing temperature was logged, as for this specific measurement we logged the set temperature to investigate its stability. Therefore, the temperature stability given in our publication is calculated from the "30°C" measurement and an additional measurement at a housing temperature of 23°C.<br> <br> To convert the measured temperature in V to °C, we used the following specs of the used NTC:<br> R25 = 1E4, B25 = 3988, Ibias = 101.055931 1E-6</p> <p><br> 2) Interference Contrast<br> ══════════════════════════════</p> <p> The file 'interference contrast_21to35.h5' holds the measured raw data for determining the interference contrast of the setup as described in Appendix A.3.<br> This file has the same structure as described in 1) and for our analysis, we only used the thermalisation with the surrounding, which starts at cycle 27.</p> <p> </p>

Loaded Waveguide Measurements of Plastic Explosives at V-Band
<p>The dataset consists of two-port S-parameter measurements collected with the Keysight Technologies N5245A PNA-X 50 GHz network analyzer operating with two OML, Inc. V-band (WR-15) waveguide transceivers in the frequency range 50–75 GHz. The device-under-test is a WR-15 waveguide shim of 2 mm length filled with varied explosive materials (approximately 14 microliter); samples include C-4, Primasheet 1000, Primasheet 2000, and Semtex 10. Data was collected in increments of 10 MHz (2501 points) with an intermediate frequency (IF) bandwidth of 3 kHz. Dielectric characterization of the materials is accomplished by analysis of electromagnetic wave propagation in the loaded waveguide by fitting to dielectric parameters and sample protrusion lengths at the ends of the loaded waveguide, for example using the method described in Z. J. Landicini, J. Barber, J. C. Weatherall, D.C. Karns, P.R. Smith, J Aparicio-Bolano, and W. Ruiz, "Loaded waveguide measurements of plastic explosives at V-band," Proc. SPIE, vol. 12535, pp. 156-166, 2023.</p>
Widening Multi-Beam Scan Angle of Conventional Waveguide Lens Antennas by Increasing Focal Points for Multi-Feed Excitations
<p><span>The paper investigates an alternative approach to improve the achievable beam scan angle of a traditional multi-beam waveguide lens antenna. To overcome this limitation, a solution of treating the waveguide lens as a transmit array consisting of non-identical elements is proposed so that each element of the antenna array can be well-calibrated to improve the maximum scan angular range.</span></p>
