Prepare the grill for direct cooking over medium-high heat (400° to 500°F).
Mix the patty ingredients, and then gently form four patties of equal size, each about ¾ inch thick. With your thumb or the back of a spoon, make a shallow indentation about 1 inch) wide in the center of the patties to keep them from forming a dome as they cook. Refrigerate until ready to grill.
Brush the cooking grates clean. Grill the patties over direct medium-high heat, with the lid closed, until cooked to medium doneness, 8 to 10 minutes, brushing with the remaining glaze every 2 minutes and turning them once when the patties release easily from the grate without sticking. During the last minute of cooking time, place a slice of cheese on each patty to melt. Remove from the grill.

Lower the temperature of the grill to medium heat (350° to 450°F). Brush the tomato slices with oil, season with salt, and grill over direct medium heat until softened, about 2 minutes, turning once. Remove from the grill. Spread the cut side of the focaccia with the rosemary butter and grill over direct medium heat, cut side down, until lightly toasted, about 1 minute. Build each burger on the focaccia with arugula, a patty, a slice of bacon, and two slices of tomato. Serve warm.
