Phase-reconstruction in photonic crystals from S-parameter magnitude in microstrip technology

A method based on Hilbert-transforms is used to reconstruct phase, group-delay and impulse response from magnitude-only information regarding the S11 and S21 parameters of photonic crystals (PC) constructed by periodically etching the ground plane of a microstrip line. Measurements show that for man...

Description
Summary:A method based on Hilbert-transforms is used to reconstruct phase, group-delay and impulse response from magnitude-only information regarding the S11 and S21 parameters of photonic crystals (PC) constructed by periodically etching the ground plane of a microstrip line. Measurements show that for many practical cases this allows us to fully characterize the devices with a simple scalar network analyser instead of more sophisticated and expensive instrumentation, such as a vector network analyzer (VNA).
