Abstract

In this work we show the capability to form various $q$-plate equivalent systems using combinations of commercially available $q$-plates. We show operations like changing the sign of the $q$-value, or the addition and subtraction of $q$-plates. These operations only require simple combinations of $q$-plates and half-wave plates. Experimental results are presented in all cases. Following this procedure, experimental testing of higher and negative $q$-valued devices can be carried out using commonly available $q$-valued devices.
