This letter describes the use of THz time-domain spectroscopy (TDS) applied in transmission to the secondary explosive 1,3,5 trinitro-s-triazine. Samples were also subjected to Fourier transform infrared spectroscopy over the same range for comparison. A detailed spectroscopy study is presented. General agreement between results from both methods confirms the absorption features found. A comparison study with computer molecular simulations shows that THz-TDS is sensitive to collective modes or vibrational modes of material. (C) 2004 American Institute of Physics.

BIOLOGICAL APPLICATIONS OF TERAHERTZ TIME-DOMAIN ATTENUATED TOTAL REFLECTION SPECTROSCOPY Gelgeç, Melis; Altan, Hakan; Department of Physics (2022-8-25) In this thesis, a Terahertz Attenuated Total Reflection Time Domain Spectroscopy (THz ATR-TDS) system was constructed to measure biological media. The constructed system driven by a Yb:doped mode-locked fiber laser had a limited bandwidth of about 0.3 THz. This bandwidth limited the analysis of various samples in the frequency domain. To overcome this limitation a method was developed so that the samples can be analyzed in the time-domain. Oral soft tissue samples collected were used in order to demonstrate...
Experimental investigation of nanofluids using terahertz time domain spectroscopy (THz TDS) Koral, Can; Okutucu Özyurt, Hanife Tuba; Altan, Hakan; Department of Micro and Nanotechnology (2012) In this study, suspensions of metallic nanoparticles in base fluids, nanofluids, are investigated by using terahertz time domain spectroscopy (THz-TDS). Nanofluids are used as the working fluid in a variety of applications especially for the purpose of heat transfer enhancement. Polar fluids are being used as the base in nanofluids for their tendency to stop aggregation and sedimentation. Polar fluids highly absorb THz signal. In order to select the best possible host, various polar liquids have been invest...
Terahertz Transmission Through Patterened Vanadium Oxide Thin Films on Dielectric Substrates AKKAYA, MAHİNUR; Demirhan, Y.; Yuce, H.; Aygun, G.; Ozyuzer, L.; SABAH, CUMALİ; Altan, Hakan (SCITEPRESS, AV D MANUELL, 27A 2 ESQ, SETUBAL, 2910-595, PORTUGAL; 2017-03-01) Patterned and unpatterned films of vanadium oxide grown on dielectric substrates such as fused silica and sapphire were grown and analysed by varying the temperature using terahertz time domain spectroscopy. After investigating the critical transition temperature near 340K, a well-known cross-shaped pattern was studied to observe any resonances upon transmission. Due to the poor conductivity of the films the frequency selective nature of the structure was not observed, however an etalon effect could be seen...
Construction of terahertz spectrometers and their use in characterization of conductivities and modulation behaviors of graphene layers / Kaya, Emine; Esentürk, Okan; Department of Chemistry (2017) Aim of this thesis was to construct two new terahertz spectrometers, THz Time Domain Spectroscopy (THz-TDS) and Time Resolved THz Spectroscopy (TRTS) for characterization of the static and dynamic properties of novel materials. After successful construction and signal optimization, system characterizations of both systems were completed with well-known samples. Possible use of ionic liquid doped graphene devices on PVC and PE substrates were characterized by THz-TDS. Devices operated at low voltages and pro...
Time Domain Terahertz Attenuated Total Internal Reflection Spectroscopy Atalar, Ataberk; Altan, Hakan; Department of Physics (2021-7) In this thesis, a Terahertz Time Domain Spectroscopy system based on the Attenuated Total Internal Reflection principle (THz ATR-TDS) was constructed in order to non-destructively evaluate materials which show high absorptive characteristics at THz frequencies and therefore prove other widely used THz transmission spectroscopy methods ineffective. The response of the system without a sample differs in amplitude and in time scale when compared to a sample measurement due to the real and imaginary parts of th...
