Novel dynamic control approach of the bandwidth of the GMRFs is proposed.

Both the spectral and angular bandwidth of the GMRF can be significantly enhanced without changing the structure parameters.

The good filtering features can be maintained as the lateral shift is varied due to the Brewster AR effect.
