Terahertz near-field imaging
Example plots of the THz near-field destribution measured at a metamaterial surface for sensing applications which is locally loaded with sample material. Left: Peak excitation state, right: 2 ps after excitation.
Our microprobe technology enables the time-domain monitoring of terahertz range electric fields in immeadiate vicinity of a sample surface with sub-wavelength spatial and sub-ps temporal resolution.
THz near-field measurements at:
- Plasmonic structures
- Passive devices: resonators, antennas etc.
- Sensor surfaces
Accessible measurement parameters
- Field amplitude
- Field phase
- Sampling position in 3-dimensions
- Direction of field polarisation in 3-dimensions (using microprobes from the X- and Z-series)
- Time (or frequency-domain via FFT)
Protemics is offering in-house measurement services at customer samples, research studies as well as technology development services.
