AngularJS filter array

Let say I have an array object

[{
    name: 'a',
    number: 1
},
{
    name: 'b',
    number: 2
},
{
    name: 'c',
    number: 3
}]

And I just want to get the name:'b' which is array[1] values. How to pass it to the filter?

<li ng-repeat="foo in foos | filter:what_to_do_here="b"><li>
