Let $F$ be a non-archimedean local field of residue characteristic neither 2 nor 3 equipped with a galois involution with fixed field
${{F}_{0}}$, and let
$G$ be a symplectic group over
$F$ or an unramified unitary group over
${{F}_{0}}$. Following the methods of Bushnell–Kutzko for
$\text{GL}(N,F)$, we define an analogue of a simple type attached to a certain skew simple stratum, and realize a type in
$G$. In particular, we obtain an irreducible supercuspidal representation of
$G$ like
$\text{GL}(N,F)$.
