  • Abstract
    We demonstrate the sensing capability of InSb based planar THz waveguide with stubs, which can sense biomolecules of a few micro liter quantity in de-ionized (DI) water. We chose Bovine Serum Albumin (BSA), a well-known standard protein molecule to investigate the sensing property. The calculated absorption coefficient from the Fourier transformed transmission characteristics show prominent changes with different concentrations of BSA, demonstrating the potential application of the device to function as a simple THz sensor.
