Abstract :
A coherent time-domain technique using freely propagating radiation bursts is used to study the submillimetre-wave response (extending to 1.4 THz) of a YBa2Cu3O7-x thin film above and below the critical temperature. From these measurements the complex dielectric response, and hence the complex conductivity, were directly obtained.
