direct current transmssion and reflection spectra of organic photovoltaic materials in the 110-160 GHz range

These are transmission & reflection d.c. voltage datasets that also have standard deviation stored during acquisition. data structured as column1: millimeter wave sweeper generator frequency, column2: transmission voltage (dc) free space/gold mirror reflection voltage(dc) , column3: standard deviation in volts dc, transmission dc voltage (with sample in path)/reflection dc voltage from sample, column4: standard deviation of transmitted/reflected voltages through, or reflected off sample
