A low-cost and planar heterogeneously-integrated 340-GHz THz imager is proposed for lensless THz imaging applications. The proposed THz imager is composed of a $16\times 16$ antenna array realized in an integrated-passive-device (IPD) technology. an IPD-to-CMOS THz interconnect. and a power detector implemented in a 0. https://chefesquipmenters.shop/product-category/rotary-glassware-washers/
