Tailoring the properties of an optical beam incident on a one dimensional metallic grating can attain a substantial control
over the excited surface plasmon polariton wave. In this work we derive the complete analytical relations between the
optical angles of incidence and the resulting surface plasmon propagation angle. These relations are demonstrated both
numerically and experimentally. Following we show that there is an optimal grating that can excite any surface plasmon
propagation angle between ±82.46 degrees and efficient polarization schemes which lead to negligible losses. Finally we
introduce a formalism that relates general surface plasmon beams to corresponding incident optical beams and using it
we demonstrate numerically a varying position surface plasmon hotspot generation.
