    Can EMP be polarized ? I think EMP is a spherical wavefront, so can it be manipulated into a uni-directional EMP, like a laser beam? If so, can anyone provide me some methods, ways of doing it... Thanks...

    What's EMP, please? Incidentally polarisation is something different from directing a beam.

    One of these things?

    An EMP consists of a great many components. The higher frequency components can contain elements of polarization.

    Keep in mind that all polarization means is the relative difference between the E and H fields in a propagating EM wave. If there is just one big low frequency EM pulse, then there's no required relationship between phases of H and E fields. If the EMP has any high frequency components that propagate out of the near field, then they will have some characteristic polarization. Generally these are a small part of any EMP, and result from secondary effects like ground-to-air reflection and resonance.
