Html.BeginForm target blank modify properties

To open a new window in Html.BeginForm(), we should declare a target="blank" but I would like to modify the opened window using jquery like change its height/width, make child focus and non-resizable. How will this be done?

CODE

@using (Html.BeginForm("Index", "Home", FormMethod.Post, new { target="blank" }))
{
        <div class="form-group">
            <input type="submit" value="Save" class="btn btn-default"/>
        </div>
}

JQUERY

    $(document).ready(function () {
      $("form").submit(function () {
        window.open('/Home/Index', '_blank', 'left=100,top=100,width=400,height=300,toolbar=1,resizable=0');
      });
    });

Thanks in advance.
