Declaring [T] (Of Type) with Powershell

I'm trying to call a method with Powershell that requires an "Of Type" or [T] according to the OverloadDefinition, Ie.

OverloadDefinitions                                                                                                                                                        
-------------------                                                                                                                                                        
Microsoft.EnterpriseManagement.Common.IObjectReader[T] GetObjectReader[T](Microsoft.EnterpriseManagement.Common.EnterpriseManagementObjectGenericCriteria criteria,        
Microsoft.EnterpriseManagement.Common.ObjectQueryOptions queryOptions)                                                                                                     
Microsoft.EnterpriseManagement.Common.IObjectReader[T] GetObjectReader[T](Microsoft.EnterpriseManagement.Configuration.ManagementPackClass managementPackClass,            
Microsoft.EnterpriseManagement.Common.ObjectQueryOptions queryOptions)                                                                                                     
Microsoft.EnterpriseManagement.Common.IObjectReader[T] GetObjectReader[T](Microsoft.EnterpriseManagement.Common.EnterpriseManagementObjectCriteria criteria,               
Microsoft.EnterpriseManagement.Common.ObjectQueryOptions queryOptions)

With C# I would declare this with <T>, Ie.

GetObjectReader<EnterpriseManagementObject>(managementPackClass, queryOptions)

If I try something similar with Powershell according to the definition, Ie.

GetObjectReader[Microsoft.EnterpriseManagement.EnterpriseManagementObject](managementPackClass, queryOptions)

Or GetObjectReader<[]>, GetObjectReader[[]] etc. It's not working.

Anyone know how to declare Of Type in Powershell syntax?
